When there is poverty people will do anything to make a living. Unfortunately some people either don't have the skills to learn how it works or lack the interest.
While they may not have heard of bitcoin - I can remember the pesobit craze last year which originated from the Philippines.
https://coinmarketcap.com/currencies/pesobit/ A lot of people lost their savings.
Unfortunately people who haven't learned the pitfalls of crypto and follow bounties blindly often also fall victim to pump and dump and other scams.
Yet -while there may be a lot of Filipinos chasing bounties - I would also like to point out that one of the top merited posters (theyoungmillionaire) on here is from the Philippines. (Probably some others too) Not only does he write good posts in English - he has also translated quite a few posts into Filipino. Hopefully the knowledge he brings to the local board will convince some of others to get more seriously involved with crypto other than chasing bounties.
There are a lot of people in the Philippines that speak a high level of English. A lot of call centers that service English speaking countries all over the world are based in the Philippines.
