Well in my country, even freelancing is not taxable and traceable as most people work online and get income in dollars or skill and other online payment methods. Bitcoin has made payment through freelancing more easy and now people can easy get their reward of online work though bitcoins.
That's some great country, believe me. I have heard of countries with 0% income tax, like Qatar, but it's among a few extreme cases. 90% of countries have income tax and it doesn't matter if you're employed by a company or running your own business.
I'd say it's worth getting paid in BTC because the chances of losing money on this deal are small, while you can really win a lot by holding. Don't act on my opinions though, I'm a gambler, I have some savings and I like my chances here. It may not be a good idea if the life of your family depends on your income.
Definitely worth it but kinda risky! I'm a freelancer too but I haven't found any work that pays bitcoin. If ever you get paid in bitcoin and you hodl, as long as the price will continue to rise then that would be great for you.
Go to the service section of bitcointalk. Plenty of work for BTC to be found there including graphics, coding, translation, social media management, advertising...
