The day-trade is one of the hardest methods to earn money in this market. Believe me, I am not a pro trader but I know how to do technical analysis and also I am following the fundamental analysis of the market. I do not recommend to anybody to day-trade. Mid-term investment is more profitable. Or just buy some bitcoin for long term
It really depends on the situation of the market, in 2017 you did best buy holding but in a bear market you will see you profits get melted away if you don't move positions frequently. The best strategy right now in my view is to tether your profits when the prices go up and buy more when they go down again. Don't even need complex analysis to do this.
