Firstly, I don't know what you mean by less developed, but I'll just consider it as a typo.
Probably he is saying developing country, saying 3rd world country or less developed is kinda harsh i guess

Well, Philippines at first were hesitant about cryptocurrency, I read some news about the government warning crypto investors to be cautious in participating in such activity, but then later the government seems to acknowledge Bitcoin as mode of payment and just the previous year a government institution (CEZA) wanted to take advantage of the current blockchain tech to enhance the country's fintech. I do not think that government of a developing country accepted cryptocurrency because they wanted to steal, I think they saw the potential of it helping the country's economic growth.
