I don't think all altcoins depend on BTC, the proof is that there is altcoins that can still survived if BTC goes down, but most altcoins follow the btc trend, maybe because BTC is so dominant in the crypto that many altcoin holders sell all their assets to buy BTC,
but few altcoins do that. mostly if there is a decrease in bitcoin, there will be a lot of altcoins that go down, especially if the altcoin is just a momentary fomo action, of course it will come back down also following bitcoin.
Simply because bitcoin dominance still high, if there's some coins who can move against bitcoin
trend is some because of the update and most are being used for pump and dump. Be very careful
if you are playing with the market, this kind of action mostly the reason why many people got stuck
and lose their money.
- Agree, before altcoins enter the market and fall into the hands of investors, it needs to establish first relationships with bitcoin and of course, once the market has determined bitcoin as the base point, altcoins can only be docile and follow bitcoin's instructions, the role in the market is not equal, bitcoin is having too much distinction from altcoins. Many altcoins may feel injustices and seek personal freedom, but bitcoin's control apparatus and investor confidence have not favored these outcasts.
