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.
A country being underdeveloped doesn't mean that BTC must be illegal there. Take note that a country may not have clear regulations about BTC and they may be hostile to BTC businesses, but until the country bans BTC or declares it as an illegal asset, you can surely send, receive and spend BTC in such a country. By the way, it is important that op understands his country's regulation on BTC, or just mention the country, let us search about it for them.
But even if OP's country banned bitcoin, I think he wouldn't have too much trouble getting his salary in bitcoin or even investing in it. Wasn't it many years ago when many countries also announced bans on bitcoin but we still invested in bitcoin despite those bans? So far we are safe, there is no reason OP or anyone else can't continue to receive payments in btc just because the government has banned it. There will always be a way for us to get around those silly bans. Because they banned bitcoin not because it was malicious, simply because they couldn't control it.
