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 think altcoins could still be use in a single store type of currency like for example a small casino or even gambling websites that have currency or their own altcoins and they are only allowing their own currency to be used in their website or just in a buyer in a popular store I think it could still work. But this kind of altcoins just needed demand and without investors, I think the price of this token will go down a lot that could instantly result in the token becoming dead in the market for sure. Surely this altcoin in the future is not meant to be for investments.
