This just goes to shows that anyone can become a millionaire if they invest wisely in crypto and bitcoin. People normally waste their investments by selling it too early and are happy with few X profits when they could literally make much more than that. There are many coins which can still make us millionaire, but we need to invest wisely.
In crypto we dont know wts the top and wts the bottom, in fact we cant say this in any form of trading. I say about myself, I set a target price on which to sell the coin usually its about 20 - 40% gain. We cant hold a coin for indefinite period of time since we have invested money and need profit for our living. IMO there is no point in hodling coin forever.
