Skilled freelancers can earn an average of $1,500 to $10,000 per month. As you are a freelancer your income is expected to be in this range which is a good amount. You are very lucky as you have convinced the company to accept your salary in Bitcoin. However Having clear communication and documentation is of course important when it comes to paying in Bitcoin. Having a system to track exchange rates at the time of payment and having a clear understanding of how any disputes will be handled will be beneficial to both employers and employees.
