I think Philippine government are just give warning to those scam project which are also using ethereum blockchain. But it will not totally stop using crypto as long as you avoid scam project. Philippine government are just trying to help the people not to scam and not to engage on such ponzi scheme. This news will not totally affect the cryptocurrency adoption in the Philippines.
That's actually their message here and not really stopping their constituents to deal with crypto. Because most newbies don't know how to approach crypto investments, they are just giving precautions towards crypto investments. But if you are already adept with crypto, you already know how to avoid being scammed by these people and not to fall with the strategies of these scammers.
I have a friend in the Philippines and I learned some information from him. The fact is that the Philippine government does not want any people in their country to be harmed. I welcome it because people are being scammed every day. In general, however, those involved in cryptocurrencies have not been much affected in the Philippines.
Most of those who are already into crypto know how to deal with scammers and can readily spot a potential ponzi scheme. And for sure, they are users here in the forum, in which, they have the access to all kinds of crypto knowledge. So they know better.
