It's feels great working and earning in crypto-currency really it's brings the world closer, I can be in Africa and working for a client millions of miles away in another country and payment method won't be a problem with crypto-currency, the world is advancing and crypto-currency is facilitating it. Anytime I put in work, and get paid in crypto-currency I hunger to work even more, it's a true blessed feeling
Yes. I think it's a big advantage for employeers from rich countries and employees from poor countries, because the first group will be having access to qualified labor for a cheaper price, if compared the to local rates of employees of their own country, which demands better payrates due to the living cost being more expensive there. Meanwhile, employees from poor countries don't bother receiving less, as even less is still a lot for the local living standards.
On the other hand, bringing employeers and employees closer, doesn't matter where they are located in the world, can have a negative impact for the masses of first world countries, because they will have difficult finding jobs which pay decently, as they will have to compete with people who are, like you said, millions of miles away in another country, for the same spots.
