Small change miner

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines

in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine

because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used

of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery

extended data

the reasons why it is not recommended to invest in IPFs are as follows:

1. IPFs technology is too early to be commercialized

IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs

There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological value

as a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened

the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state

It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems

The ecological application space of

IPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling

3. Zecx has not been listed on any exchange or any authoritative digital currency information platform, so it is likely to be MLM currency.

4. Zcash, which is called zero coin in Chinese, is known as the most anonymous digital currency in the world. Bitcoin was once in the limelight, and its price was second kill. But then all the way down, the concept stock is no longer a myth, it still needs time to accumulate. Now, the price has fallen to about 300 yuan
there are platforms supporting zero currency trading in China, such as cloud currency, bitcoin, and foreign P network
however, this kind of digital currency still needs careful investment, and the risk is too high, which is different from the fixed income token launched by European crowdfunding platform.

5. f'( x) If = 3x ^ 2-A
is an increasing function on R, then f & # 39 x)>= The results show that 0% is true
and F & # 39 x) The minimum value of F is F & # 39 0) = - a
so there is - A & gt= 0
get a

6. Are you talking about virtual currency
if it's virtual currency, what kind of currency do you want to dig, BTC or eth, LTC or big zero? Different currencies, different algorithms, the corresponding mining machine will be different, the price will be different (the size of computing power, different brands, the price will be different)
if it's traditional: I don't understand.

Because Aidou game box was developed by Guangzhou Heimi blockchain Technology Co., Ltd. It is the first application of BGC (blockchain game coalition) game ecological chain. BGC is the abbreviation of this company, which is why it is called BGC application

in 2018, Heimi blockchain launched cmel electronic competition version of black shark game mobile phone, and built in Aidou game box. The platform embedded blockchain token concept, combining traditional game platform with blockchain technology. Therefore, Aidou game box is a biological application of BGC blockchain

extended data:

Aidou game box is equivalent to the exchange of the blockchain instry. As long as there is a transaction in the game, Aidou will draw a handling charge, but there is no other share. After the intervention of token mechanism, the circulation of all aspects of the game instry will be more convenient and fast

Aidou game box provides the function of online red envelope transfer. Players can complete the transaction between legal currency and token. Of course, they can also buy on the outside exchange, but the price fluctuation will be slightly larger

you have to pay as much RMB as you want to play traditional game props, and the love bean game box can be set according to the price of the token, and it is a free trade between players. If you have a good feeling, you can sell it cheaper, which is money saving for players
