LETF STRATEGIES

Has anyone seen the video on YouTube re LETF Strategies? https://youtu.be/gcdsBmIt3KQ?si=8YveHyHWFJPKGc2X

Does it look like there’s one that would work well?

Does anyone know of a good one for trading TQQQ, SOXL and FNGU?

The 3X LETFs seem to be where there’s the best potential for making money. I know I couldn’t do buy & hold, and expect I’d get hurt bad trying without a good strategy. If one of the strategies in the video is good, it would help to know. Has anyone tried any of them?
