I think 10 years from now I'll be retired from working. Living off crypto income. That's just my idea. 10 years is enough for exponential growth. Took 10 years to become a millionaire maybe less with 333 bitcoins. That's only a 1000$ invested. I got like 6 coins with 1000 each invested. I think my chances is very high. While I'm adding more coins like dent, Electra, universal, nuls . its do or die time.
10 years from now many altcoin in coinmarketcap will surely die because many of them have no real usage. While some of them will stay specially those who are on top 50 altcoins. I also believe that there will be a regulation in cryptocurrency that will minimize shitcoin and only legit altcoin will remain.
