If they get some crypto for stuff they do anyway that's a much better way of introducing crypto / Bitcoin to average people.
and who is going to pay you for things you already do? and what is he benefit in it for them to pay you?!
what you are saying sounds more like one of those micropayment jobs you usually see advertised on the internet which are a complete waste of time and could even infect your computer if you follow their instructions including visiting random sites! they advertise it like "things you already do" then you see you have to do mundane tasks for long hours to make a cent!
One of the examples is Wirex, where you get a cashback for all your purchases with the credit / debit card in Bitcoin. There are other credit cards with cashback systems, but also a lot of credit cards without.
Another example is Lolli, a cashback system for online purchases that pays in Bitcoin.
Microtasks could be a thing, but there you have to explicitly do something you probably wouldn't otherwise do.
But in general the fact that I can't come up with more examples is the precise reason why I'm posting this question ;-)
I am kinda sad that a decade after Bitcoin came into this world, people are still asking where they can get Bitcoin in exchange for the things they can do. The gigs economy that uses Bitcoin should have been big by now but unfortunately the whole thing failed to take off. Fiverr should have added cryptocurrency as one of the choices to pay and get paid but it has not. This big question is driving at the heart of the problem when it comes to the adoption in the grassroots for Bitcoin. We have to be honest in saying that there is a failure in here, and which I am hoping can soon be fixed.
Wirex may not be working globally and even if it does not all countries will have many merchants participating in the cash back program not unless Wirex is going to be establishing a real presence in each country. Microtasks sites that deal with Bitcoin failed to get critical number of clients and maybe they can be closing soon or shifting their focus from cryptocurrency back to the traditional way of payments. Microtasks should have been the best way for many people to acquire Bitcoin but I still have to see one that is really making a good volume of business.
