Not all prop deals are bucket shops and sim platforms.
The prop industry has changed a lot in the last 20 years though.
It looks as though both Top Step and Earn2Trade are no longer ET sponsors. As none are a sponsor, if I were to go the sim trade pray for pay route, I'd choose Apex over those two.
I saw a video a day or two ago on youtube about yet another firm called TradeDay. From what I gather, that firm does seem to be a bona-fide remote prop firm and not simply gambling sim demo treadmill operation like the rest of them.
