Any idea what this is about??

I had a look..seems copying CBBC in Hong Kong. https://hk.warrants.com/en/index

This is the exchange: https://www.acdx.io/

I looked at their Twitter and website (ACDX). Not much information. But from what I've learnt they are like a new FTX rising. I got into their Telegram group, seems to have a high threshold of investing. So wondering anyone has any workaround here.

have no clue. Only developers may know?
