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?
Altcoins are not the only coins that are being used in gambling, even Bitcoin is used in gambling, and majority of the gambling platforms makes use of Bitcoin than they do with altcoins. I dont see any use for altcoins in the future except for what they are being used for this time around which is investment and making transactions.
