I don't think getting paid something like 80 cents on the dollar is worth it. Why don't traders just open another account at another leverage exchange like Binance Futures or Bitmex. Then go 100x their account when they think BTC is going to go up and basically try to get liquidated on OKex and get the entire sum on the other account minus fees on both exchanges.

This is actually what many traders did in Poloniex who had their accounts frozen from withdraws for over a year. The leverage was smaller, I think 3x so it would take a lot longer however given the volatility they should eventually get it done.

Apparently their CEO was arrested before in the past and nothing came out of and they resumed operations. So most people are expecting the same outcome.
