Do they trade worldcoins?
They will trade, once opened - according to twitter quite soon - many alts to worldcoin and back. For traders, there might be arbitrage opportunities.
Especially new exchanges might have these opportunities because the markets are not liquid usually in the first days.
I have nothing to do with this exchange - do your own due diligence - so if something goes wrong, do not come to me whining. I just thought to share this interesting new service.
