Hello, recently one of the most famous traders Tone Vays said that next bull run will cause altcoins crash because people will start with the massive sale of altcoins and they will put everything in Bitcoin.
Do you agree with him? Really only Bitcoin survives?
I agree that often it is bitcoin that leads any recovery, but I think it is an absurd claim that all altcoins will fail and only BTC will survive. This means that either the purposes of alts (smart contracts, fast payments, IoT, privacy etc) are irrelevant, or else that BTC can provide all solutions and do so better than all alts in every case. I really don't think that's true at all.
