Nice question, because i have a few people who have 7 am - 6 pm shift such people have all their time spent on their job and energy drained so how do such categories of hard working people be able to add another side hustle that is still requires alot of time to do that, although i encourage multiple jobs to generate cash flow that can be used to buy bitcoin.

Anyways the guy story may be true and he can be abke to accumulate such amout of bitcoin vai DCA approach and sure we know that, is not every body that can do two jobs but if it work for you why not go along with it.
