No doubt if employer and freelancers both agree Bitcoin may a popular method for remuneration for the work done.
This is both convenient for employer and employee, and when crypto will become more popular as a payment method, it will also help for the freelancing world to grow.
When I was still new in the online world, I wasn't so interested as in some freelance job, it normally requires a verified paypal to receive the payment and needs to open a bank account to have your money in your bank account, this method is quite complicated compared to just making an online wallet or even an exchange wallet where you can make even without a KYC, hopefully this kind of improvement will happen in the future.
