I join a lot of Filipino Facebook Group not to scam because my purpose of joining them is to learn some information that can help me about crypto. Don't trust too much because not only filipino can scam it maybe your friends or someone you know. We are educated people so we must avoid people that you think a scammer.
I don't understand why you would join a Facebook group to learn about crypto. The information is all overmthe internet and wiki. Also this forum, although it's harder to find info here.
Th Philippines is a nation where people are starving with $1/hr wages. They are desperate for a way out, and so are the scammers. They'll scam the desperate.
