When my portfolio has risen about 50% i take out 10%. (5% in euro wallet and 5% in new ICO's)
Well this is a good strategy. You are holding I think and you don't do day trading.
Since this is trading discussion, what I will share is my strategy in trading. Since I'm doing scalping, I only make my trade when I got 1% profit already then I will find for another coin again. In this way, you can get more profit but on the other hand, it will be more risky and stressful.
