Altcoin season is here and it will probably continue if bitcoin prices don't fall on a large scale. While bitcoin continues to get a lot of support from various institutional investor making it difficult to drop in large numbers, this will help the altcoin to continue growing.
I second that too, since Bitcoin will prolly continue to appreciate in price, and ethereum for example has been known for following Bitcoin price movement, so it's an indicator that eth and few other good altcoins will see better days going forward.
Dex cryptocurrencies in general is garnering more trust; people and Investors, even institutional Investors now believe in the potentials Bitcoin has to be a currency, Investment option, a hedge against inflation and other whatnots and this trust is definitely going to shift to the altcoin network, with coins that are willing to develop their ecosystem.
