Are there other Bitcoin endeavours one could be interested and invested in, other than trading and mining?
Of course there is. In my opinion, it will also benefit you if you adopt bitcoin as a means of payment in your real or online business. It's worth a try as long as your country and government have legalized it, but if that doesn't then try another way.
I'm not dealing with trading and mining, that's already been explained by many other users - but something different like staking or something is also profitable. Instead of getting too confused about the best option, I think you're only better off as an investor if you have the good budget. Bitcoin price is still too low so far compared to the previous ATH, so take this opportunity to buy and hold it long term.
