I read it does exists trading platforms were if you earn money they lose it because they launched the order internally between their affiliates, and not to the external trading networks (or whatever they are called). This if they even really launch the orders...
We can not see the traders' internal code so anything can happen. I think they look like money-collecting machines. Take care guys.
Edit: Wow, that downvote sounds very interesting, as the first that I pointed is widely known, the so called "Market Makers".
Trading platforms would make more money if you made just enough money to continue to trade long term. Especially the bucket shops crypto and forex exchanges that make most of their money front-running customer orders.
Unregulated exchanges are just a way to bring back the bad old days of "boiler room" penny stock scammers of the 80's. Most of the people making money are running 40 year old scams on 20 somethings who don't know better yet.
