Your trading style depend your mindset & skill. For newbie, I believe they will take day trading as their style, using 30 - 60% from their coins to make profit with medium time period but for expert usually using 50 - 80% from coins with long time period. Because I don't have much time, I decide to use expert style ( not because I'm expert ), to not wasting my time in front of pc. Buy/ sell/ hold depend your target and stop loss, when reach the area just take action, for me 2 - 3 month is enough. Have a nice day.
