If you check in this way you may get into any scam exchange! Better you be careful and learn which is top exchanges in the crypto market and plan accordingly. If you own any unworthy ERC20 tokens keep it in wallet and wait until it boom. It may take long years also. LOL.

If you have fund means I suggest you to go with the Bitrex, Bitfinex and Binance. Here you will be find big volume and you can find the good coin which can grab more volume into it. So be careful and invest on the right exchange.
