When my portfolio has risen about 50% i take out 10%. (5% in euro wallet and 5% in new ICO's)
Well done in doing your strategy. But as a trader, when I gained profits, I invest it again with another coin. I am just withdrawing some of my profits when I badly needed money for emergency cases only.
Technical analysis, fundamental analysis, support and resistance levels, trend lines and discipline 
What's this? Is this your strategy?'why don't you elaborate those things for it to be clear enough to understand? Sharing your knowledge is caring. Your shortcut comment is vague.
