Doge>
if all people took a few minutes to do research before using this exchange I doubt that until today they would continue to exist, they would have gone bankrupt due to lack of customers. unfortunately people don't do research before using these exchanges
I use them to exchange some tokens listed only there. It has been for a long time. As I remember due to their very high Bitcoin withdrawal fee, I always turned everything into a doge and move it from this exchange. but that was at a time when the value of the Doge was much lower.
as far as I remember many exchanges stopped Doge transactions when the hype started, Binance also at one moment. many never even returned Doge chain, (like Hitbtc) and I tend to believe that they misused users' funds. due to the high value, releasing these funds would cause them losses.
