I do know a person wich is helping others with crypto offering them a source of income, the thing is that at some places the income from signatures as well other works is enought to they survive, soo they are doing the best they can trying to be at signatures, but those wich arent able to join are doing others tasks to get their daily income.
Yes, but it is pretty much all about what place are you living in.
If you are living e.g in US or Australia, you are not going to make a living only on signature campainings. The payment is way too low, and you would have to break the rules of signature campainings, because it is simply not possible to live thanks to just one account, even on legendary rank.
In my opinion, saying that bitcoin reduces unemployment is not so smart, because it is still not so popular to say things like that.
The percentage of people using it is simply too low to make any significant change on world employment rates, but Im sure that it helps many people with getting their funds for monthly settlements. You can simply use it as a second source of income, and i think this is the smartest thing you can do because relying on bitcoin as an only source of money is very risky: unless you own some kind of company that gives you constant profit over longer course of time.
