If it can be done simultaneously, of course, as you said, it is very good to do Although both also to produce what we want. Although currently, bounties are very unpredictable because they always disappear and don't pay, but doing is something that needs to be done, and we don't know what the future will be like and who knows it can pay well.
But once again, I do agree more with focusing on investment and trading and still making bounties if it can be done, because everything will always be able to provide surprises in time.
Yes, it depends on you. If you can't do both of them together, it is better to focus on one of them. But I prefer to do both because I think it is very possible and won't spend too much efforts. For investment, I only need to know when the right time to buy. I also rarely buy, I only buy when it is a big correction (dump). But for trading, I often buy and sell almost every day. This needs bigger efforts because I need to do both technical and fundamental analysis. I also target for the profits in a short time. So, it is harder because the profit target should be faster. But I have no problem with this, so far everything is good.
Yes, in the end, it all comes back to the individual, because not all will be the same when doing it, like you who can do it together. Of course, it's very good that it can be done, because it will make it easier for what you want to achieve quickly,, but if there are those who are not able to maybe they also need to adjust themselves so that they can follow you in time, let it process well.
Extraordinary, what you are targeting is certainly not something easy, but because of strong determination, then nothing is impossible to do well. Hopefully your profit target can be realized quickly.
