Bitcoin does not need altcoins.
Unfortunately it does.Suppose there were no Altcoin, people would switch back to fiat in bearish times and chances of them coming back to btc were less. Now they have an alternative in Altcoin and any fall in btc price is comepensated with the rise in Altcoin price.
But yes there should not be hundreds if Altcoin. I think only 20 would have been better.
not really, what you say is what traders do. they pull out and go to another market (altcoin market) and make profit to come back but others who aren't day trading don't care about it. so altcoins aren't really needed.
and i disagree, hundreds should exist because you can't pump only 20. people will give up. but when you create new altcoins every now and then everything refreshes and starts anew.
