I'm sorry for all the ones looking for speculations, this is not the purpose of the thread. I want to hear from the community about which coins will be making a difference in our world over the next few years.
I think the coins that will change our future will be the ones that are leaders of this market now. I mean ETH, XPR, EOS, XLM, LTC, USDT, ADA, IOTA, XMR. The made history, they are top coins in terms of price by market cap and offer many advantages and some of them move blockchain technology forward.
It could be, those with recognized abilities should indeed be an altcoin that can change the blockchain world to be better one. With the best blockchain technology, of course our lives can change drastically with the help of these technologies. Just for sure, one day, one of them will present something new.
