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.
