When BTC falls, most altcoins follow it but when it rises altcoins do not with less force. The last year is proof. With the naked eye, we see the devaluation of altcoins!
yes, that's a true fact. The BTC is still now the most dominant coin and certainly its price effects to the market. So when it fails the altcoins follows it. But when it increases then the traders try to sell the altcoin and go back to the basis-BTC. That's why I think that situation happens.
The attitudes of most traders are still the same it' all about how to quickly earned so we are seeing this movements as the market still dominated by bitcoin and each movements this coin go it's been chased by traders, there's a need of much stronger pumped before we can see diversions from big earners and lift up the alts community.
