Bitcoin commemorative coin

1.

Are you talking about this? It's not worth collecting

bitcoin is a kind of virtual currency, and some people make it into physical objects. This can be regarded as a kind of commemorative medallion, to put it bluntly, a toy

2. Bitcoin [1] is an electronic coin proced by open source P2P software. Digital coin is a kind of network virtual asset. Bitcoin is also paraphrased as "bitcoin.". Bitcoin is based on a set of cipher codes and generated by complex algorithms. This rule is not interfered by any indivial or organization and is decentralized; Anyone can download and run the bitcoin client to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P distributed network. The generation and consumption of each bitcoin will be recorded through the P2P distributed network and informed to the whole network. There is no possibility of forgery. Bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized characteristics of P2P and the algorithm itself can ensure that it is impossible to artificially manipulate the value of bitcoin by mass manufacturing, The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This ensures the anonymity of money ownership and circulation transactions.

3. The essence is different. First of all, commemorative coin and game coin have their issuers, while bitcoin is a decentralized free coin, which determines that its value is not controlled by any personal platform. The former can not be circulated or can only be used on a small range of platforms, while the followers of bitcoin are all over the world. Many foreign online platforms and offline merchants accept bitcoin payment. Steam, a well-known game and digital media platform, has accepted bitcoin for payment. What's more, bitcoin has been rising rapidly since 2009! Suggestions: go to haobtc to buy a few coins and hold them for a period of time. Anyway, there is interest in them, so it's good to invest

4. No, because it's not a real commemorative coin, it's just a handicraft or a toy

5. Starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 6] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation group through a huge amount of calculation. This equation group is designed to have only 21 million special solutions, so the upper limit of bitcoin is
21 million[ 6]

ask why

is valuable
it must be easy to understand and not too complicated

6. What I see on eBay are basically foreign sellers, but few in China. In addition, Taobao also sell, but do not know whether it is true or false
I hope the above answers will help you.

7. tolerable. In fact, the miner can still find someone selling.....

8. From the perspective of circulation, only bitcoin can be regarded as currency, but only used as virtual currency
other types are just articles, which actually have the property of gold and silver circulation
the concept of money should be clear. To put it simply, it can be used as a transaction voucher when goods are in circulation.
