I have kinda gone through this. I am holding a 100x and put in 500 ish in the beginning.
I still feel there is room to run but I have taken out my initial investment x3 and have put those 3x500 in other projects I think might do the same.
Take some profit along the way, but keep some to let it ride. Do not get too greedy and appreciate the gains you have made.
RE: When the price of the tokens you hold goes up 100x+ within hours, you'll test yourself...and your limits. Can you handle it?
