I think having only a single source of income that you are using to take care of your expenses and investment is far better than plenty source of income that someone can not use to take care of their expenses and investment and a lot of people are into this category of people that can not..., and someone who has more than one source of income and knows how to manage his investment and take good care of their expenses is also great. Every individual should know their capacity and know the kind of job they can handle and the kind of job they can not handle, overstressing oneself because of our investment and expenses won't worth it because the moment one break down, is either they use the money he or she has worked for years to take care of the person or the person might even die leaving all the things he or she has worked for that's why it is not good to overstress.

There are multiple jobs that an individual can work that are stressful no doubt but makes you more  agile, I had two friends some years back, one of them had two jobs, he was a Bar man at a night club and he also had a street marking job for a particular brewery which makes him to go out on the street and advertise several drinks to shops and retail owners so they can buy, he does this throughout the morning everyday and  goes home later in the day to rest, in the evening he goes to the beer parlor that he serves as a Bar man, stays there for couple of hours before going home, so I asked him one day if this multiple jobs he is doing not stressing him, he went on to say, no that the job actually makes him agile and strong to go out everyday. However I also have another friend that works in the office 9  to 5, he has his own front desk and a laptop, his pay is fine, enjoy the ambience of his office and always talks about it, however there's one thing that I notice whenever we are having a conversation, he always complains about the fact that he is tired whenever he comes back from work, sometimes he doesn't even have to strength to make food to eat, he just goes in to sleep.

So this is to say that there are multiple jobs that do not necessarily break you down, sometimes it sharpen you activities and make you get ready for the following day because the agility is there.  but one thing is that anybody can fall sick, whether you are doing multiple jobs or not. More so if you can do multiple streams and keep your income high so you can maintain a good investment portfolio then I don't see anything wrong.

Boils down to the kind of stuff you are into, they are some folk that are okay with just having one good paying job that can cover their expenses and same time enable them to invest without having any stress. Having more than one sources is also good but still don’t over push yourself because health is wealth . There are some jobs that are draining , so is still good to watch your health too , just like they always you can be aggressive but don’t over do it .

Not all work is physically demanding, although all work can be time-consuming because all work always requires time. But as long as a Bitcoin investor's work still allows them to continue investing, I don't think it will directly impact their physical health. There are many people in the world who still work two different jobs, yet they are still quite healthy and have no problems in their lives. Anyone who has become an investor, especially an investor who frequently buys Bitcoin, would be better off if they could have more than one job because they could easily utilize the income from both jobs for themselves and could also directly apply it to Bitcoin investments more regularly without any obstacles.

Yes you are right but if you find a second source of income and work to invest it is very good. But you have to take care that you do not harm yourself while doing this work. For example, many times our health gets very bad while doing a lot of work. And later we become very sick, work by considering all these aspects. Remember one thing, the richer you are, the more you spend. So if you can do extra work then continue working if you cannot then change your decision. Because you want to do this to invest extra but if you get into a big physical problem then your investment may be at risk.
