If you’re gambling regularly while also investing, it’s probably smarter to use stablecoins for gambling. That way, when the bull run hits, you won’t be regretting all the Bitcoin you lost. I’ve personally lost a decent amount of Bitcoin, so yeah, it hurts a bit. Even if you set aside Bitcoin specifically for investment and gambling, it’s still Bitcoin, and its value could hit $100k soon.
Sorry to say this, but I don't see the correlation here except that you do not want to let go of past losses, you should think of the conversion then as if you gambled fiat, so let go. If you want to invest in Bitcoin, do so, and if you want to gamble, do so, the two are not the same unless you just want to have enough of Bitcoin in your gambling account and be wagering little by little from them with the scope that you are also investing. In that case, you need to differentiate gambling from investing (which I don't even advise) because there are different accounts for that purposes.
