consumption. This figure was higher than the yearly 
power consumption of nearly 160 countries or 
regions, including Iceland and Nigeria. If all the 
Bitcoin miners around the globe were to form a new 
country, its power consumption would rank 61st in 
the world. ((Sources: power compare) 
3.2  An Exchange Medium 
Currency serves as a medium of commodity 
exchange. In the exchange process, the sellers convert 
their goods into money, and then use the money they 
received to purchase new goods. Here, currency 
serves as the exchange medium that enables goods 
circulation. 
Bitcoin is favored by users due to its 
decentralization, high anonymity, transaction 
irreversibility, perfect traceability, and low 
transaction fees. Many people regard it as a safe and 
effective means of payment. But we still need to 
remind you that Bitcoin still poses some concerns: 
First, the Bitcoin system generates a new block every 
ten minutes and only at this time, the transaction 
record loaded on the blockchain will be preliminarily 
confirmed. The transaction will be further confirmed 
once the new block is connected to the previous 
block. Based on the technicality of the Bitcoin 
system, the transaction could be truly and irreversibly 
confirmed only after the confirmation of six new 
blocks. The means to truly confirm a Bitcoin 
transaction takes about an hour, which is too slow 
compared to the current centralized payment system 
that only takes seconds. The slow transaction speed is 
closely linked to the underlying technical design of 
the Bitcoin system. Second, a block is 1 M in size, 
which is big enough to contain around 1,000 pieces 
of transaction information. This means that a large 
amount of transaction information will be temporarily 
stored in the transaction pool to be confirmed. This 
would prolong the transaction time, posing great 
limits on the number and scale of transactions being 
conducted simultaneously. Third, every node in the 
Bitcoin system must keep a copy of the entire 
blockchain, and this chain is still getting longer, with 
one new block added every ten minutes. Currently, its 
size is even bigger than the storage capacity of any 
personal computer. Many Bitcoin users have to seek 
help from the supercomputers in large institutions, 
which contradicts Bitcoin’s decentralization nature. 
Since deficiencies like this were developed out of 
Bitcoin’s decentralization nature, they cannot be

trading system. The solutions to those problems are 
still unknown and under discussion. 
3.3  Store of Value 
Currency as a store of value refers to its being 
preserved as a symbol of social wealth when it is no 
longer circulated on the market. It can adjust the 
amount of currency being circulated. Only authentic 
and pure gold and silver, in the forms of coins and 
bars, can be kept as a store of value. When kept in 
banks, paper money can be seen as the symbol of 
one’s assets, but it can never be a store of value. 
People will only keep paper money only when its 
value could remain stable for a long time.   
Bitcoin does not possess any value in itself, so it 
can never be a store of value like gold and silver. 
Though the total amount of Bitcoin was set to be 21 
million, some people insist that it has high resistance 
to inflation. However, two shortcomings that exist 
with Bitcoin make it almost impossible for this 
cryptocurrency to become a store of value. On the one 
hand, there will be only 21 million Bitcoin in this 
world, but our total economic and social production 
capacity is far greater than this. We all know that 
Bitcoin can be divided into eight decimal places, so it 
seems possible for it to satisfy the transactions of the 
whole society. However, owners of Bitcoin, seeing 
the rising trend of Bitcoin prices, would not use their 
Bitcoin for transactions. Instead, they will hoard them 
and wait for them to appreciate. An American 
economist, Paul Krugman, once wrote: “What we 
want from a monetary system is not to make people 
holding money rich; we want it to facilitate 
transactions and make the economy as a whole rich.” 
“Due to the expectation that Bitcoin economy will 
grow, people will tend to hoard the virtual currency 
rather than spending it,” resulting in “money-
hoarding, deflation and depression.” On the other 
hand, when Bitcoin first appeared, only geeks 1 
would collect this virtual currency, leading to today’s 
excessive concentration of Bitcoin. As reported by 
Bloomberg, nearly 40% of the world’s Bitcoin is 
owned by a thousand users. “They have a great 
impact on the Bitcoin market. They are known as 
whales.” If Bitcoin can serve as a store of value, it 
means nearly 40% of the social wealth would be in 
the hands of these one thousand people. Obviously, it 
is  unacceptable  to almost any economy or society.
