You claim that your country is an underdeveloped country so we can assume that bitcoin is not legal in your country, if bitcoin is not legal then it will be safe for you to pay salary through bitcoin. Just saying from my opinion about bitcoin legality because as you mentioned your country is underdeveloped and as far as I know underdeveloped countries never accept bitcoin. It is a very good decision if you proceed with caution. Accepting payments through Bitcoin instead of accepting payments in local currency is another level of thinking. If you accept payment through bitcoin, you can hold that bitcoin for a long time if you want, and if you want, you can sell your btc through P2P. Undoubtedly, you have taken a commendable initiative.
Not all underdeveloped countries ban bitcoin, and as the OP said, he works remotely for a company so paying in BTC won't be detected by anyone. Even converting btc into currency will not cause any difficulty for him. But what I wonder is, did the company he was working for accept his offer so easily? And they're going to set up a bitcoin payment system just for him? I don't think anyone should get that priority unless he plays an important role for the company.
Some people have raised this point, is it really hard to buy BTC for someone who lives in a developed country? I understand that there are some documentation stuff that you have to go through once, but that's all. Buying and sending it is pretty easy. My employer is in England. I know we have this belief that credulous people have some inane apprehensions about crypto and its mostly true belief I guess. But these guys work with computer technology and have a lot of knowledge about it. Its not like I am convincing a grocery shop owner to do it.
And also to add some context, I am not the only employee who is from another country. They have a lot of employees like that (pretty standard practice for web development agencies all over the world). They haven't dealt an employee with crypto before, but I am sure they have dabbled in lot of payment methods and are very open. I think you have to be if you are employing people like this.
