Don't believe everything you see online, mate, as most of those online testimonies are all fabricated stories from content creators and some so-called influencers as a means of attracting traffic and members to their channel. The time when bitcoin lifted most people out of poverty has long gone, as it's hard for you to even see 2 times your invested amount on bitcoin in this period without holding for a long period of time.
Holding and trading over your job could be considered unwise financial decisions. Holding Bitcoin does not give out an immediate profit, for one should focus much more on buying and holding than the profit he or she is to make in a short period of time. Buying and holding Bitcoin don't benefit holders in an instant, and as such, it can't sustain a jobless individual; instead, it will make you panic sell when you are in need.
As for trading, it will require a great deal of dedication in order for one to do that, as it will require a lot of perfection, which I believe no trader is perfect, and as such, losses could be expected most times during a trade, and when such time comes, you will be left with no option but to save or lose it all, taking a greater risk.
