I sold ~ 25% of my position today. This is exactly the amount of money I put into CYDY during the end of last year. That means my remaining position is my profit. A very good feeling, particularly as I hand the money to my oldest daughter who will use this to buy her dream apartment. Opportunity popped up out of nowhere, Daddy´s chance has come to do something valuable.
On the one hand, I know that I will (very likely) renounce profits, on the other hand this stock has quintupled in no time and even if risks seem to be ridiculously low, one never knows. And my position is still large enough to not have to work for the rest of my life if things progress (as ohm20 predicts).
