I seek criticism. I support Bitcoin. I have to say that it is difficult to find the correct argument against Bitcoin on the "buttcoin" reddit. I saw some negative news articles about masculinity about certain regulations and other news that seemed to be bad for btc. But there is no basic discussion. What I found so far are these:

The price fluctuates greatly, or there is no hedging, it is a bubble

Has not been accepted yet, you cannot pay in most shops

It faces a serious defect that the government/people are unwilling to give up the right to print money, so they will stop it in some way.

Thousands of coins = inflation. I don’t think this is true, because every POW system with a smaller computing power, Bitcoin can theoretically be "cracked" by the computing power provided by btc miners, plus the computing power can be comparable to any other computing power in the world. Comparable. Compare with the network or supercomputer, do it yourself. )

I find that some aspects are not good, such as it will—if it succeeds—change or collapse the economy through partisanship. Just like now (as far as btc is concerned) there is almost no inflation, and there is not much incentive to spend money or use btc. (In my opinion, this will have a positive impact on the environment, because people will not waste money on useless and short-lived products) Of course this is an environmental view, but all the energy is directly used for password security and The immutability provided by BTC (as far as the US dollar is concerned, it is not secure-it is only determined by supply and demand) so it makes it more resilient and almost impossible to be hacked. In my opinion, this is like a fair accounting system. Although you have to compare it to a traditional banking system, all these buildings and ATMs and anything else required by the banking system are running around the clock.

I would love to hear some constructive criticism. Personally, this seems to be a system that will continue to exist (but at what price, it may rise).
