Take back 5k. There is capital and profit, the rest is floating.

Capital 2k5u doesn't know how to play, you just buy this many and hold, then close the app since last August. Now it's 12k and the rope is about to break, should I take profit or not? My friend says no, it's just starting now, but I'm feeling too stressed.
My brother bought at 0.8
Zro around 2.4
Scr 0.6
I don't remember the demon manta for a long time.
