$OM is very likely the same as before. After the leverage adjustment of OM on Binance, low leverage now requires a huge amount of capital to maintain the strength of long positions. Originally, it was enough to buy 10U with 500 dollars, but now it requires 100U. The price for maintaining the contract market-making has increased tenfold. The market value of this coin is not low itself.
It is also possible that the exchange is colluding with someone to take away this lucrative asset from OM's market.
Only the exchange can change the rules. Before OM's plunge, there was an announcement about the minimum holding position, which only targeted OM and XRP. One can only say that this is all a conspiracy.
