I believe this is due to regulations. It’s crazy to me that people are complaining about a service which can give them a chance to trade real money without any track record. You can put yourself through all the tests using TOS free paper trading account. The real problem is that, just like any other retail trading service, most of their customers are gamblers.
So it comes down to a simple choice - provide service with understanding that 98% of your customers will fail. Or not provide the service at all.
REGULATIONS? Regulations you say!?
