I think bitcoin is very good to hold in the long run, because bitcoin can be mined out and of course the price will potentially be very high, but on the other hand people won't wait too long for that to happen, so they prefer altcoins which has a much faster movement
Yes, it was but sometimes people never think about it instead they'll become more practical in a way that investing in altcoins will multifold their money for many times far from what they could get from Bitcoin. Kinda crazy right? But as a natural person, that is what we are absolutely be thinking of. We can't ignore this possibility that people are jumping off from Bitcoin and finding their bigger chance on the altcoins. But sooner or later, they be going back to Bitcoin.
