No.
Hope, or rather greed and delusion, springs eternal. The higher and more dominant BTC gets, the more shit there'll be scrabbling in the mud claiming its turn is next. In terms of shitcoins we ain't seen nothing yet.
There's a near infinite supply of the stupid and greedy. Shitcoinland may go deeper into obscurity. It's never going away.
The latest bull run proved that the situation can be quite different. When Bitcoin starts growing really high, altcoins go after it. Some of the tokens gain (in percents) even more than BTC.
No mate, it's not the same case this time as I believe that whatever we expect from crypto markets, it does always opposite of the same and when big players already know that there's not much steam left in the altcoins' trading game and all the money is being shifted to margin trading for much better returns, this time it'll prove to be a lot more different than before. I don't say that alts may die completely, but the way many of then were overvalued, it's time for them to see the real action by the whales who will put innocent people into traps again (the way they had been doing so far) and then throw those alts into graveyard by making their values go least in USD and BTC alone will rule.
