You remind me of myself a few years ago when I was naive and thought a 100% return in crypto was incredible.
Go for it, but remember this golden rule: never ever look again at the price of JWL once you are totally out.
Avoid it at any cost, because if you don't and it turned out JWL went hyperbolic like the very comparable BitCrystal it will haunt you for the rest of your life.
i know that feeling too It will hound you everytime. It is better to get the 50-70% invested btc back and wait the right price of jewels. The more you willing to risk the investment, the higher reward you will get. But better take care of your heart hence sell some to get a portion of invested btc
