An exchange platform that gets into the crypto sphere without having anything tangible to offer its users happen to be nothing lesser than a Ponzi scheme. A Ponzi scheme is any project that is out there, on the market, looking for benefits for itself only and forgetting about the users or people that actively use their platform. An example of such a platform is the Royal exchange platform.
This is a platform that was meant to be an investment platform but turned out to be a Ponzi scheme. The platform, instead of looking for how to be of assistance to people that use their platform, went into the crypto market for the sole purpose of satisfying their own financial needs. Using this platform isn't beneficial and I would advice all traders to keep off.
