In the same vein it is natural to assume that the death of the altcoin world would eventually do only good to Bitcoin in the long run as people won't be losing money anymore. So what d'ya think?
I don't agree with it, bitcoin rise this high because of altcoins, so if altcoins will die, people may invest in bitcoin but will not be as aggressive as before.
The market is big, people are looking to diversify their investment and I don't see any reason why altcoins should be eliminated when they offer great idea and they are building it for us to use in the future.
