After this halving time, market will take correction. But now day trading is profitable at least for next 2-3 months. Everything is on dependable on market conditions, whatever is it day trading or ICO investment. I know so many traders whom earn good money in good market but lose in same coin in bad situation.
Day trading will be profitable as long as there is volatility in the market. And the closer we get to halving, the more volatile it becomes. This is the best time to trade, when the price of bitcoin for 1 day changes by 10%. But at this time, compliance with risk management is an important condition.
