When my portfolio has risen about 50% i take out 10%. (5% in euro wallet and 5% in new ICO's)
if i were you i have withdrawn all my holdings. 50% is already a big profit. unlike me, my capital was loss for over 90% i have never seen my coin to gain even 5%. i just hold my coin until now. maybe if i get even a little amount I will immediately sell my coins.
