I am an experience trader as i traded on most exchanges that are listed on coinmarketcap. Today i will show u my experience about crypto exchanges, The most exchanges that are listed on coinmarketcap are generating fake volume to attrack the traders attention when u deposite on these exchanges and try to buy or sell your coins u will see that your order is not clearing even in high 24 hours volume, The example like these are coinegg bleaxy systemkoin and fatbtc.Some of exchanges have very bad customer sport when u face a problem there they take several days do solve or pay no attention on your problem examples are p2pb2b mercatox coinsbit and ooobtc. Some of exchanges went scam and now stealing people funds they donot give u withdraw be careful and do not deposit on these example, Bitebtc Yobit coinbe bitinka. i advise u to trade only on major exchanges like binance bittrex Kucoin. Have a nice day
