Please refrain from sharing information that is not your genuine experience with our service. We process a lot of orders daily and stop transactions with really high risk score because we don't want dirty coins to be exchanged via our service. We have no intention to deliberately withhold coins of our clients as you said. We want to remind you that all users agree to our Terms of Service and Privacy Policy before exchanging, and we do not have any hidden information regarding the rules of our service. All exchanges are verified on BestChange via video call and a discussion of the exchange's system, we are not an exception. Most aggregators request registration documents, and we provide them to these services, so you can be sure that we are a legitimate entity.
