We can say that this is Bitcoin's time. The time of alts is yet to come and so, investors only pay attention to Bitcoin and push its price up.But why since 2018 until now when bitcoin has reached $ 11 707, ethereum is still $ 227. The ethereum price should be $ 585.
What happened
if bitcoin price is $ 20 000 then ethereum price is only $ 600 But I believe there will be price adjustments and there will be many whales selling BTC to buy ETH and other top alts.
