Look, the 90% profits sharing ratio is great and you should not accommodate for anything less since it exists
But this trait itself is not what seals the deal. You should consider a platform that is reliable and reputable.
The Ultimate Traders is exactly such a prop trading firm.
If my comments and experience with the platform are not enough, then check other reviews, too… you will see plenty of them confirming that the platform pays out the profits and can be trusted.
Long story short, I recommend Ultimate Traders as a reliable prop trading platform
