the dominance level of bitcoin was close around 55%,
wrong!
"dominance" of bitcoin is still up there near 100% as it has always been for years and that has not changed that much. maybe it dropped to 95% at some point but it is still up there.
what you are quoting is not "dominance" it is market cap share which is meaningless and only coinmarketcap.com calls it falsely "dominance".
It simply means more people are getting their money away from altcoins and moving them to BTC for multiple possible reasons.
wrong again.
traders aren't going to pull their trading funds out of the altcoin market just because they are getting dumped. traders know well enough how to make money in that market from the pump and dumps and their funds will remain active there.
the reason why the market cap share of bitcoin is increasing is the same reason why it was decreasing. because altcoins market cap is fake and easy to rise so also easy to drop.
when a coin has 100 million coins in fake circulation and its price goes up $1 its market cap goes up 100 million. but when bitcoin price goes up $1 its market cap only increases ~$17 million.
for instance when ETH got dumped another $100 down to $300 range it simply lost $10,125,000,000 ($10 billion) market cap in a blinking of an eye.
same with XRP. a $0.2 dump meant it lost $8 billion market cap.
this is how fake market cap is! and this is why it shouldn't even be used in first place to compare them.
