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?
Gambling is a big industry and the use of blockchain technology and cryptocurrencies to fuel it have made the industry to expand more in the cyber community. Other future industries that can make use of altcoins are online shopping and games. E-commerce websites are continuously expanding and the gaming industry most likely won't fall because there are always clients.
