What for? You should specify your reasons why you are looking fo filipino community members. Or else they will not get interested about your queries.
Also are there any big Telegram chat for Philippines crypto users?
I don't think so there are lots filipino bitcointall users here. It is impossible to gather a large number of people in one place. Maybe small groups is possible.
Some of Filipino also do not always or not active at telegram so there's a possible that the group chat on telegram can be lost and can be inactive.
There are some telegram group that I saw but because of inactive, they decide to erase it.
