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?
Yes altcoins will be useful in the future because altcoins is useful now for trafing to have profit.and its the easiest way to earn money now.Just monitor anf learn how to do it.
it's true the problem now is that many people see altcoin having a bright future, so someday altcoin is very useful in the future like bitcoin. and most importantly, we must always deepen the knowledge of the crypto world
