Bitcoin is attracting a lot of money and driving up altcoins.
After a general market correction, Bitcoin attracted funds to rise again, followed by other altcoins.
This process will be repeated, and there may be off-market funds entering during this period to boost Bitcoin's rise.
These off-market funds tend to invest only in Bitcoin, and the rise of altcoins is more of an emotional reaction.
At present, the market's confidence in Bitcoin's breakthrough of new highs is already quite strong.
