No, altcoins I have followed made big rallies. Bitcoin and altcoins rise together. If Bitcoin make it to 10k USD then I expect Ethereum at least 1k and also for all other tokens similar raise.
Exactly.
Bitcoin rise is always very good,because other alts will rise soon too.
BTC dominance from 1 August is still the same 49.8% (according to Coinmarketcap)
That means everything is growing.
