Good strategy for the short(ish) term if you are a trader, we seem to agree!
In the long term though (5+ years), I believe that BSV has, BY FAR, the best chance of survival and mainstream adoption. But hey, don't take my word for it! I'm sure you won't.

Always do your own research, your own due diligence!
That's interesting. Why would you say so? The mainstream don't seem bullish at all on BCH, and much less so on BSV. What makes you think the script will flip in the long term?
To play devil's advocate for a moment, you could have said the same thing about Bitcoin until pretty recently. In fact the mainstream is still quite skeptical. From my perspective, BCH and BSV are pretty shitty fundamentally and don't have bright futures, but I've been wrong about altcoins many times before. A few years ago, I never would have thought Ethereum would grow as large as it did. Who knows?
I'm okay missing the boat on the BTC forks though. There's plenty of opportunity and BTC isn't going anywhere. I'm only stacking BTC, ETH, and a few sleeper alts for the next altcoin bubble.
