Their trading volumes went down because whales left that exchange. Currently there is less than 90k BTC left in their main cold wallet, and this for such a 'large' exchange is very alarming.

The premium there indicates that there is a lot demand to sell USDT for BTC and withdraw directly after. It wouldn't surprise me if we see another 10-20k BTC being withdrawn from their main cold wallet this week.

Anyone still using that exchange is a retard--you're basically begging them to pull off a scam on you. The only thing this exchange should do is disappear from this ecosystem. Today rather than tomorrow.
