If one were to buy and hold solid avaerge coins (not a coin that kicks out and gets 10000% gain), but rather a nice steady gain like eth, Ltc etc (top 20) and starts with 10k, is it possible to reach a million without trading and buying/selling at highs and lows? If so, how long would you predict it would take? Or are most coins not going to last long term, so every 6 months would I have to rebalance with newer coins?
It very possible and actually most of the millionaire born from cryptocurrencies are those who just bought and hold or some accidentally held their coins and caught by surprise in the sudden growth of bitcoin in value. I think it would take years of patience and a dash of luck for it to happen though.
I have whitnessed by myself. One of my friend made his first million dollars from ethereum already. I actually started to crypto currencies because of him. I am hoping to achieve the same that he did it.
