This round of altcoins did not follow the rhythm of BTC, which only indicates one thing.

The cryptocurrency market has entered a mature stage, with big capital focusing on BTC and Ethereum.
These two assets will definitely not have any issues. It wouldn't be surprising if BTC reaches ten million per coin in the next four years.
Altcoin shrinkage started from 2018 and 2019, as old players in the crypto space grew into big players, moving on to play with BTC and Ethereum. New small players have their bank card limits blocked and cannot enter the secondary market.
The lack of domestic small players and their belief in altcoins is the biggest reason for the significant shrinkage of the altcoin market after 2018, and it actually has nothing to do with the Federal Reserve.
Now we are just waiting for the country's policies to open up, which may be the last bit of unequal information advantage for old players in the crypto circle who haven't made money compared to stock players and traditional finance players. Once everyone is in, this circle will be just like the stock market.
