bitcoin is being used in so many places throughout the world but it can be so much more. It's obvious that there are so many freelancers in every country. Firms, companies, startups etc.. have a limitation that they can hire freelancers only from their country since they can pay them only in their native currency to avoid hassle of exchange. But if firms, companies, startups etc.. start using bitcoin as a payment method to hire freelancers then there will be so many opportunities for the freelancers since they can get work from anywhere in the world. I don't know why has this not become a huge thing until now. This could really change the life of freelancers and give a better end result/product to the company they are working for.
The only problem here is that people think that crypto or lets say bitcoin is too much volatile and it's very risky for them as those freelancers tend to earn their bread and butter online from the freelancing websites and when the amount that they are earning is varying depending upon the market then they will face problems financially and also in supporting their families.
But for a person who is just doing freelancing as a side gig, getting paid in bitcoin can be a great source of investment.
