It is not that bitcoin cannot die, 'cause such is life, then you die', but it will be a king of crypto for a long, long time ahead. Though this is not the question asked. Here, in this topic, I'm interested in altcoins, and it doesn't look like bitcoin is going to kill'em all. If it were so, they wouldn't have appeared in the first place, right? So there is an evident need for them. whatever it might be, for example, purely speculative interest.

But how many altcoins do we actually need? Maybe a dozen, maybe half a dozen as most coins and tokens are obvious pump and dump schemes that don't even last beyond their ICOs if there is an ICO at all.
