Yes, for me a quick flip is dumping 80-100% within a short time or more exactly like when price is 3-5x, Ill sell them and move on. Sometimes may not even wait for them to reach a major exchange. It depends on the token, what I think about its likely short term/long-term prospects, and how much it has risen. Thats my goal, not sure how u think?
Enough in taking out the initial amount and letting the rest ride essentially gives you free tokens and of course anyone can buy back in later after the coin dips. But psychologically can be stressful if you cash out shortly before the coin starts a huge run.
