sometimes people try to take profits and find themselfs buy on high ;)

I like to daytrade, I have been studying the cryptomarket and sometimes its hard to keep up to it but I have found its volatility to be very profitable if card played the right way. I am not saying its easy but it can be done. you just have to read a lot and make a strong investment plan.

of course one should not use all your money to day trade, only 40 or 30% the rest just buy and hold

I agree, trading is fun, that's why you should split as you wrote 30% for trading the rest long term. or however each person sees it
