Cutting a 50% loss is too much.. Instead, just forget about that trade and focus on another opportunity for now.. You can check on it from time to time in case price has improved.
Bouncing back from 50% loss is not impossible in crypto market trading world, you can clearly see that some coins rebat with 100% gain on its price based on my little experience on trading, I'm not that good or expert with this kind of trading but I manage to witness some coins pumps over 100+ percent like bitcoin and eth over a short period of time. Holding the right coin is the key for you to cover all the loss of 50% because if you manage to hold some useless coins from PD and scammer groups then you may have to shift to another genuine crypto.
