Hi, fortunately, I lost no more than I can afford; I made a deposit in the BiteBTC fraudulent exchange, fully trusting the CMC authoritative rating. (about 0.1 BTC, end of November 2018, 36th place in the rating, stolen on January 1, 2019). I think that in the loss of coins by thousands of customers of the BiteBTC exchange, there is an indirect fault and CMC. Thank.
It's not a rating but a ranking, based on volume. That says absolutely nothing about the reliability or trustworthiness of a platform.
