The only place I think altcoins has a future in is gambling, normal gambling but first and foremost e-betting.I can not see how it will take over from normal currency's in the world of buying or selling any other goods then btc. The main reason I think this is that nobody wants to be that guy that bought two pizzas for 10000 btc 5 years from now, so i cant really see what else it has a real future in. But that is only my opinion, What do you guys think?
I'm not over sure but this case was in 2009, almost 10 years before from this year. This will not repeat in cryptocurrency because that pump isn't possible to every coin. By some altcoins top coin list could change in future but I think Bitcoin and Ethereum will stay in top position. Top coin history always changing in Cryptocurrency history.
