Best trading strategy advice

A saying the higher the risk the higher the profit has pushed many into futures and ETF trading without proper knowledge of how it works. I was introduced to crypto by a friend who successful profit by shorting FTX and I got inspired to try my luck, but I didn't ask him how he got there, and I paid dearly with my first attempt at shorting BTC thou I later found out it was a mistake.

I became skeptical about crypto and later find out that DYOR is very important and understood Futures and ETF trading are for professionals in the space not for novices, so I decide to try spot trading and bought MX, TON, and ETH. Recently, I decided to try day trading in this mini bull run and made some bucks which have now ignited the spirit that led me to crypto, but I am curious about the best strategy to employ.
