If in trading apply fast trading strategy,
What obstacles are constraints
and weaknesses?
Yes. I do it whenever I have the free time. It is very time consuming for watching up and down of the price. You should not used for 100% of your coin as it is too risky. Only trade with 10% of your coin. Quickly sell when the price is high a bit, then buy again. You need to control your feeling. Dont be too greedy. Just do it as a fan.
