and make sure you have stop lose, so that your capital does not run out
How long do you want to keep setting stop-loss for a new token that has just been listed on exchnage? It is most times better to monitor it, since it is still fresh in the system. In fact, trading it that way can give you the opportunity to make more profits than just setting a stop-loss.
The time you also gave, in my opinion, is very short. A coin that behaves well on exchnage, usually have an incubation period, a time that it is being prepared For a surge or upward movement.
