Being a good investor, sell a partial amount of HEX (you choose what you're willing to "dump" and how much do you want to keep based on your faith in both - the project and the team). I believe that trusting blindly on something can cost you what you're already gaining, so it's better to be happy with what you already have. If you were to ask this for YFI (yearn.finance), I'd still say no because the way it quickly went up, the same way it'll get flash crashed one day soon. It's not about the DeFi itself but the craze behind it, and once it settles, you'll regret why you didn't bother to sell at the time when you've had $300k already on your hands. If you think 50x is less and you are going to get a jackpot hit through this coin (though, remember this that nothing could beat BTC ever), please keep holding and wait, but don't wait too long that you don't even get your initial capital. This isn't about pessimism against this token or any other tokens, but the fact that it is already too high to wait for.
One of the easiest things to do in this case will be to sell half of your coins and to keep the other half, while this option is not the most profitable it is the one that is the safest, that way if the price of the coin crashes you still got incredible profits out of it that you can use to change your life or to keep investing, and if the coin keeps skyrocketing then you keep getting profits, to me that strategy is the best of both worlds but unfortunately it cannot be applied by someone that is blinded by greed.
