as kindly explained to me by @fitinfun a few days ago: Just pick a point and take out a percentage - 10%, 20% etc. These gains are so huge you can afford to take some off the table to feel more safe and secure. Then keep working with what you have left in the game
I've also tried my luck in daytrading but after a few bad decisions I just managed to break even, so especially for newcomers I really would recommend not to gamble. And as always, in case of doubt: hold
Okay, thanks.
