What wallet does Germany use to buy digital currency
ways to purchase digital currency:
at present, digital currency is more like an investment proct. Due to the lack of a strong guarantee institution to maintain its price stability, its role as a measure of value has not yet appeared, nor can it be used as a means of payment. As an investment proct, the development of digital currency is inseparable from trading platforms, operating companies and investors
trading platforms play the role of trading agents, while some play the role of market makers. The profits of these trading platforms come from the current expenses and premium income of investors trading or holding digital currency
1. Investors need to register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time
2. Users can use the money in their cash account to buy and sell digital currency, just like buying and selling stocks and futures
3. The trading platform will sort the buying and selling requests according to the rules and start matching. If the requirements are met, the transaction will be completed
4. Due to the difference between the trading volume submitted by users, the trading request can be partially executed
take RBM operated by professional operation company opencoin as an example: ripple protocol was originally designed based on payment method, and its design idea was based on acquaintance relationship network and trust chain. Using ripple network for remittance or loan, the premise is that the payee and the payer must be friends or have common friends. Otherwise, the trust chain between users and other users cannot be established, and the transmission cannot be carried out
extended information:
the characteristics of digital currency are as follows:
1, low transaction cost
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment of high handling charges to payment service providers
2, fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, and it does not need any centralized organization similar to the clearing center to process data, so the transaction processing speed is faster
3, high anonymity
in addition to the physical form of currency can achieve peer-to-peer transactions without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote peer-to-peer payment, and it does not need any trusted third party as intermediary
both sides of the transaction can complete the transaction in a completely strange situation without mutual trust, so they have higher anonymity and can protect the privacy of the traders, but at the same time, they also create convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
anmao wallet
anmao wallet is a light wallet developed by Hangzhou anmao blockchain Technology Co., Ltd., which saves storage space compared with the full node wallet. And it is a multi currency Cross Chain Wallet, which supports BTC, BCH, LTC, ETH, etc, dash and erc-20 series of tokens. At present, it is the most complete currency digital currency wallet in the true sense
anmao wallet is the only digital currency wallet that supports Chinese mnemonics. It is composed of 12 Chinese characters, which is convenient for memory and in line with Chinese reading habits
the biggest feature of anmao wallet is that it well applies the scalability of light wallet. While managing a variety of digital assets, it has embedded DAPP list and anmao fishpond mining game. The tokens are directly stored in the wallet, which is convenient, labor-saving and interesting. It can be said that it is a wallet that will make money
with embedded Android block browser, each transaction can be queried in real time by using transaction address, block height and transaction ID, which is accurate
there are also market and information DAPP, a multi-functional digital currency wallet
deficiency: no trading function
imtoken
imtoken is a digital currency wallet that supports eth, erc-20 token, bitcoin HD wallet, isolation witness, EOS and other tokens in EOS main network. A set of mnemonics can create wallet accounts in multiple currencies, thus saying goodbye to the complicated backup management. It is a Multi Chain Wallet
imtoken supports the sending and receiving of digital currency and the currency transaction of Ethernet series. With the help of blockchain intelligent contract, it does not need to trust a third party to complete the currency exchange directly at the mobile terminal. Token management function is easy to operate, automatically discover tokens, and no need to add them manually; It supports one click search and can easily view and manage multiple tokens
the private key of imtoken is self-contained, which further guarantees the security
deficiency: imtoken only supports digital currency based on eth main chain, and tokens of its own public chain such as BTC and CTC cannot be stored. It only supports eth as a service charge when transferring, which has some limitations
bitpai
bitpai wallet is a new generation of blockchain asset comprehensive service platform developed by bitpai team, which is based on HD wallet technology, multi signature and on chain transaction. It can easily and safely use digital currency and easily send and receive bitcoin on bitpai. At present, the main supported currencies are BTC, BTC, ETH, some erc2.0 tokens, qtum, HSR, dash, safe, LTC, LCH, Zec, etc and Doge
bitpai supports multi address coin issuing, built-in OTC and exchange (third-party service), and can trade with users from all over the world, which is more suitable for professional users of coin circle who trade frequently and have OTC demand
in terms of security, the user controls the private key, and after the transaction, the coin is directly kept by the user. If it does not operate for a long time, bitpie will automatically lock, further improving the security of the wallet
deficiency: for initial users, too many and complex functions are a kind of burden. They only need to send and receive digital currency simply. Too many complex functions increase the learning time cost of users and affect the experience of wallet users
wheat wallet
wheat wallet is a digital wallet that supports eth, Neo and EOS token at the same time. It has built-in face, voiceprint, living body and other biometric technologies to ensure asset security, which is unique in the current wallet
wheat wallet supports the interfaces of mainstream exchanges such as coin an, fire coin, gateio and okex to automatically obtain position data
the UI design of wheat wallet has a good experience for users in human-computer interaction, interface logic and beautiful interface. The first operation can know the functional process, in an intuitive way to let users understand how to interact with the software, the interface design has a wheat uniform style
deficiency: there are few supported currencies. In the application mole, each application or active section is the width of a mobile phone screen, with a maximum of 2.5 applications displayed on the same screen. Although it looks very generous and beautiful, it will be cumbersome to find an application, and it needs to slide down continuously
atoken
atoken is a mobile wallet supporting multi currency cross chain exchange, which is safe and convenient. At present, it supports BTC, LTC, ETH, etc, Doge, EOS and other main chain currencies; BCD, BTG, BCH, SBTC, etc; Support all tokens of Ethereum erc20
users hold their own private key, which is stored in app with multiple encryption. They do not access the server in any form, and no one else can touch your digital assets; The wallet adopts 5-layer HD, horizontal isolation and vertical defense architecture; Pbkdf2, sha-512 and other encryption algorithms are used. At the same time, atoken implements the transaction acceleration function of wallet and supports the transaction acceleration of bitcoin and Ethereum
deficiency: there is no market information in the wallet, so it is inconvenient for users to use
in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety
take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:
1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.
firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required
then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers
Second, the bank system verifies the financial level motherboard and encryption chipuses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area
Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fastthe reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency
Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank you1. Security risk of running environment
the core file of encrypted digital currency Wallet - private key / mnemonics is stored on the terminal device, whether it is PC or mobile terminal, if the terminal device appears unsafe phenomenon, There is a very high security risk for the private key / mnemonic
at the beginning of design, a secure digital wallet can avoid the possibility of private key / mnemonics being stolen e to the running environment. The security problems of the running environment on the terminal mainly include virus software, operating system vulnerabilities and hardware vulnerabilities
2. The security risk of network transmission
the security of network transmission is more reflected in the ability to resist man in the middle attack. Man in the middle attack means that the attacker creates independent contact with both ends of the communication and exchanges the data they receive, so that both ends of the communication think that they are talking directly with each other through a private connection, but in fact the whole conversation is completely controlled by the attacker
although most digital wallet applications use the HTTPS protocol to communicate with the server, the man in the middle attack method is to get the content of the HTTPS protocol by installing a digital certificate in the user terminal
a secure digital wallet needs to be able to scan the legality of all the digital certificates in the terminal, check the proxy settings in the network transmission process, and ensure the security of the basic network communication environment
in the development of digital wallet, whether to use two-way verification for communication verification at the network transmission level is also an important criterion to measure the security of a digital wallet application
3. The security risk of file storage mode
for the private key / mnemonics of digital wallet, the storage mode of terminal device also needs to be paid attention to in the security design. The access right of private key / mnemonic file directory, the form of private key / mnemonic file storage and the design of encryption algorithm all need to be strictly designed
when we analyze the security of several mainstream digital wallets, we find that even the well-known digital wallets are random in the storage of private key / mnemonic words. There are both plaintext storage and encrypted storage, but the decryption key is fixed in the code, which can not play any role in security defense
4. The security risk of the application itself
the security risk of the application itself mainly focuses on the security defense of the application installation package itself
whether the application installation package has the ability of anti tampering is a very core technical ability. In addition, memory security, anti debugging ability, life cycle management of private key / mnemonics, security of debugging log and security of development process also need to be enhanced
5. Security risk of data backup
if the mobile application can be backed up, it can use the machine with more powerful computing performance to brutally crack the private key / mnemonics. For example, if android:allowBackup Property is set to allow backup, then the backup mechanism of the system can be used to back up the application data files, and the private key / mnemonics of the encrypted digital currency will be backed up to the external media, which breaks the security boundary design of the operating system from another direction
for the majority of users, the security of digital wallet also means the security of wealth, so we must be careful when choosing digital wallet
I have used several wallets such as coin letter socoin and coinplus
in terms of personal experience, socoin and coinplus are very simple and easy to use. They are not only decentralized multi-functional cross chain digital currency wallets with social functions, but also integrate Multi Chain multi currency wallets, payment and settlement platform, currency trading platform, social groups, information market and other functions, which can meet almost all your needs for digital currency in one stop.
Generally speaking, the user experience of light wallet is relatively good. Generally, it supports multiple chains and is easy to operate. Light wallet has been used geek wallet , which is not bad. It supports BTC, EOS, ETH, usdt and other mainstream currencies
if the amount involved is relatively large and it is stored for a long time, it uses hardware wallet, which is relatively safer than light wallet and needs to buy hardware, The operation is relatively complicated
As the price of virtual currency led by bitcoin rises, more and more people join the mining instry. This also led to graphics card prices soared by 100%, causing many people's attention. In fact, the soaring price of graphics card is e to more and more miners, as well as some vendors' cards and the global chip shortage
Third, the global chip scarcity
e to the global chip scarcity, to a certain extent, it affects the price of graphics card< after all, the manufacturing of graphics cards cannot do without chips, so once there are problems in the chip instry, the graphics cards will naturally be affected as chips are scarce in the world, the proction capacity of graphics cards is insufficient, and the number of graphics cards in the market is scarce, which leads to the rise of the price of graphics cards
generally speaking, the sharp rise in the price of graphics cards is related to the increasing number of mining people, the number of vendors and the shortage of chips. If you are not in urgent need, you are not recommended to buy graphics cards at this time
