Should be similar like other countries anyway, like other countries does it might need KYC for taxation purposes on trading or purchasing, the volume plays a huge impact but of course there's many cases where illegal activities are facilitated by cryptocurrency and was cracked down by authorities, cryptocurrency would perserve a location like another other financial instrument tools for a small group of traders
In Southeast Asia, in my opinion, not all countries are willing to accept bitcoin, especially countries with high levels of corruption, because decentralized bitcoin will make it difficult for corruptors to carry out their actions. But countries like Singapore, Thailand or the Philippines can accept bitcoin because they believe that tourism can grow more if bitcoin is legalized, even though when bitcoin is withdrawn, it still needs KYC.
