If you have successfully gained 50x from HEX, you should immediately sell it, because if the price drops suddenly you will lose
the opportunity to make a profit. But if we pay attention to the HEX trading chart the price has already dropped right now, now it
has dropped around -7.65% and this is an opportunity to buy HEX again, if we want to investment in the HEX project. Because
the current price correction from HEX is deep enough so buying HEX at the current price is the right decision.
I do not know why this is even a question anyone that invested a decent amount of money in a project and then gets 50 times his investment should sell a significant portion of their holdings, that way you lock your profits and in the case the coin keeps going up you still have some of those coins that you can sell in the future for an even bigger profit, but I do not really know what are the goals of the OP when it comes to his coins maybe he's expecting to get 100 times his investment.
