Hi! Great topic, so I wanted to add on the company i saw recently, even if they are active for some time now: Level01 (https://level01.io/) peer to peer (P2P) derivatives exchange that allows investors to trade options contracts directly with one another, without requiring an intermediary or broker.
I would recommend being careful with exchanges and companies that make fake claims, such as "AI-Guided Derivatives Trading" - there's no AI to start with
Then it says "Partners & Global License" and lists "Bloomberg, Reuters" and couple other fancy names or supposedly regulatory bodies, while simply having logos but no links or anything. While we can easily dig deeper with this one, from the surface it already shows that there's no need at all - as it's quite obvious what it is. So while someone might want to try this, be advised - it has typical signs of scam exchanges, which can be used for marketing purposes, or for scamming you. Be careful with this one.
