my opinion in the next 5 years will be many coins that fall and many new coins that come to the surface but only the strong ones will survive. I believe in ethereum.waves.ripple.monero. will survive the next five years and have a very good prospect.
Yes, I think so that Altcoin Will last for the next 5 years . As if all coins has Its own purpose and vision to Go on to fulfill their goals. Bitcoin is Very strong And if other coin could follow this , no doubt that they can also survive for many years.
