I agree with you, simply good news are always welcome! I opened the article that OP shared, it's about Binance adding support for the Bangladeshi (BDT), Czech Koruna (CZK) and Ghananian Cedi (GHS) to the Binance Peer-to-Peer (P2P) trading platform against BTC, USDT, ETH, BNB and BUSD with zero transaction fees!
There's no mentioning any kind of adoption in any of these countries! Their laws are probably more opened for crypto, which is a good thing for crypto users from these countries, but it's too early to talk about legalization of crypto!
Maybe it is too early to legalize bitcoin or other crypto in any country that has a conflict with bitcoin and it is very fortunate for those who are in countries that legalize bitcoin and there are also some who allow bitcoin or other crypto as an investment, but are prohibited if used as a transaction whatever, like in the country I live in, and Bangladesh prohibits it because it avoids money laundering and hopefully all countries can legalize bitcoin or other crypto after studying it well.
