I live in an underdeveloped country, but I work remotely for a fairly good web development agency. We don't have a lot of financial services/wallets here, so we had to go circumvent a lot of obstacles for me the money to get to my local bank account. This whole process took a hefty fee, and time. And the worst part is the currency is absolutely shit and deteriorating (even compared to other fiat currencies),
Recently, I convinced them to start paying me in BTC. I save what I have to save, and convert the rest to fiat via P2P trading. Its so quicker and I get great deals, no more bullshit. I think this has been a great benefit of crypto for underdeveloped nations.
I have been accumulating bitcoin from a long time from my freelance work, but getting paid in it by my regular work feels awesome!
Since you are working remotely and on the freelancing job, it makes it easier not only for you but for your employer as well, to give you payment in bitcoins. It would save him a lot of additional cost if he uses the bank transfer or other third party services like Western Union etc.
However, if you were doing a physical job in an office or in a multi national company, it would be impossible if the employer may accpet your desire to pay you in BTC. It is because usually the employer has similair methods of paying salary to the whole company employees, and they do not change it for only one employee.
