You're trying to compare Binance with what you're boasting about as the 2nd. Let's say pre markets volume does speak a lot but if it's stability and actual volume of exchange per se, you'd for sure say that the one that you're laughing is the first of them all compared to what you want to bring up on this thread. I don't know how long these pre-market trends are going to stay but maybe you're having a good time on it and say that you're making good money on it without any attachment to the exchange that you're working then good for you. But about the quality of exchanges, then look for other sources that speaks total volume, the ins and outs of each exchange that you've mentioned and see who got it first since pre markets are just one of their thing.
