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.
My thinking is don't wait for 10 years because that is too long to guess what can happen. Instead, try to sell whenever you think made a good profit and try to back the same amount of coins at a lower rate. Because as we all know crypto market after a bull run it will correct a lot so if you do this correctly then you can achieve your target much earlier than 10 years. At first, you can do this experiment with a partial amount of your investment and if it works for you then continue or else just go with your plan. I wish you good luck....
