Now a days all alt coin markets has been dumping and dumping without any simple pump for the btc price increasing.So just i want to know that can bitcoin destroy the maximum type of alt coins market?
I do not think that it can happen. Because it depend on the coin itself and how much supporter it has got. Now in any point there will be no case where the coin is not being supported by anyone and all of them ran away to get more bitcoins, this is not going to happen so as to things can't get worse with altcoin.
Bitcoin is different thing or different part of investment and just because it is going very high doesn't mean people will leave or abandon the alt coins completely. There are so many ways coins can be invested and this will keep going on ever and ever over the time and thus no coin will get dumped to death if it is in the top 50-100 lists. Thats for sure.
