No matter how difficult a full-time job is , we will still need it and it is an important part of our lives. If someone has no job or no source of income, I also believe that they will not be able to invest in bitcoin or will never invest successfully if they only borrow to invest and do not work .
I can't agree with that. Besides full-time job, there are many other ways to earn money, and quite regularly. Take trading, for example. If you do it well, you can earn not only as much, but also much more than a full-time job. This is especially true for countries with poor, collapsing economies. Then you can invest, not necessarily only in Bitcoin. There are many options for short-term and medium-term investments, the profit from which you can live on and reinvest the investment body.
