I do not think the crypto market will survive only on bitcoin without altcoins. Bitcoin and altcoins are two parts of a coin. So they cannot survive without each other. But seeing the market situation where only bitcoin is taking off, I am forced to believe that altcoin season will never come. It may be my illusion I wish.
l would really like to point out, by and large, l can not imagine altcoins without BTC or BTC without altcoins. It is a something chain reaction, in the crypto industry, there are two parts, BTC and altcoins. But l don't agree with your speculation and we must believe it that, altcoin season will come, it is my candid advice. It is not an illusion, it is highly likely that it will happen. Don't worry about it, a bit more patient. It seems it will take heaps of time.
