Yes you should believe in the bitcoin because it has a great fiuture and it will grow a lot more so its just a matter of time before the bitcoin will become very popular!
This why many people are starting to use bitcoin for we believe that we are going to have a great future with bitcoin. And for those unemployed people instead of looking a real job. They are just working with bitcoins by different ways like trading, gambling and as well as selling their services to the people who needs it.
If Im unemployed and still have strength to work on real lije job, I will not rely on bitcoin. We should take advantage of bitcoin if we really believe on the future of it. So what shall we do? Save most and spend less of bitcoin. If we only have bitcoin earnings, it will be primarily used for daily spendings that meant for fiat earnings.
If those unemployed really can't find a real life job in most of the cases like students, disable one etc then that it's acceptable.
