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?
Lol, I think there is a purpose for every altcoin that is being created and they are just going to serve for those purposes alone, and some of them might not be successful because I know there are lots of projects that usually fails, only a few will stay for long and there will still be more coins being created every time with some of them being a replica of what has been done before. Bitcoin will always be at the top and it will be seconded by Ethereum. These two are really good and the way I see them, they have really come to stay.
Maybe few altcoins may survive to exist and to serve its purposes and all other altcoins may get vanished over the time as they were not created with an uniqueness. When we cannot be sure about one coin's purposes then how we can assume about its survival in this highly competitive crypto world.
