Could you please elaborate on the regulations and guidelines that govern the TKO platform? Are there any specific requirements or restrictions that users need to be aware of when engaging in transactions or activities on TKO? I'm particularly interested in understanding the policies around account verification, trading limits, and any potential fees associated with using the platform. Additionally, I'm curious to know if there are any specific rules or guidelines in place to ensure the security and fairness of the trading environment on TKO.
