Firstly, you using an exchange site or an exchanger (a person who buy and sell through p2p or on this forum) have to start with you grusting the exchange site or exchanger and to know they actually don't lie you have to check their review and feedbacks but I will advise you not to use exchange site that is not listed on CMC of coingecko cause there are fake exchange site that can also fake review.
