(1) its better to buy low and hold some good coins rather than day trade.
(2) holding for a period of three months may give good returns.
(3)Technical analysis wont work in day trading(intraday) if any whales enter a coin.
(4)sentiment and fud news impact market more than any whale.
(5)if you made profit day trading on a particular candle move,sorting on other candle may take away all your money.
(6)stay away from fake pump and dump groups.
Happy investing.
