maybe the best would be to stop offering the offsite feature for Investors
Why? In case that didn't come across well: An investor that misuses the system by lying about how much offsite money he is prepared to risk only increases his own risk. He does not pose a danger to other investors.
Offsite investments are an amazing tool for responsible investors and using them is entirely optional. I do not believe they should be removed just because it is possible to use them improperly.
why? just to have a healthy Investor environment that would be good for the site. Investors who are misusing the system are hurting themselves and the site who gives them the option. they are actually gambling and Investors shouldnt gamble IMO
but you as the owner can do whatever you like. I dont and didnt accuse you guys because as long as the Investors are not scammed out of their investment all is fine IMO
