I think I also share same views as of yours. I only trade few pairs and so far I've made profits on those pairs. Sometimes I do test out new pairs but most of the times I avoid new pairs and stick to the ones that I trade mostly.

I mostly trade Bitcoin/USDT and so far that has been one of the most profitable pair for for but yes I do trade LTC, Solana, TON, ETH, and a few other pairs. I traded Not Coin when it was added to Binance and made some profits with that but if I had hold that then I could've made more profit with that one.
