When my portfolio has risen about 50% i take out 10%. (5% in euro wallet and 5% in new ICO's)
Everyone has their own strategy, some people prefers to use the strategy of taking out their whole money and starting anew, while others will prefer to be pyramiding into a winning trade or the taking the big profits and leaving the small loss. The first is what I use, I dont waste in taking out all my money whenever I see that the market is up and Im making a huge profit. For me thats the best profit and thats what works for me, you have your own decision to make.
