The American cryptocurrency exchange Poloniex reported that financed margin trading users lost 1800 BTC (about $ 14 million at the current exchange rate) due to a sharp drop in the CLAM rate and extremely low liquidity of this coin.
On May 26, a sudden, severe price crash in the CLAM market caused a number of margin loans to default, resulting in a roughly 1800 BTC loss in the Poloniex BTC margin lending pool for non-US customers. Today, we recognized the generalized loss across lenders in the BTC margin lending pool. As a result, the principal of all active BTC loans as of 14:00 UTC today has been reduced by 16.202%. This impacted 0.4% of Polo users.
According to the representatives of the exchange, on May 26, the so-called Flash crash of the CLAM (228th place by market capitalization) occurred, as a result of which the coin fell by 77% in less than an hour.
Rate collapse caused a wave of liquidations designed to reduce losses and repay loans to lenders. Poloniex claims that 0.4% of the total number of users of the exchange suffered, and the volume of the marginal lending pool decreased by 16.202%.

First, the velocity of the crash and the lack of liquidity in the CLAM market made it impossible for all of the automatic liquidations of CLAM margin positions to process as they normally would in a liquid market. In addition, a significant amount of the total loan value was collateralized in CLAM, so both the borrowers’ positions and their collateral lost most of their value simultaneously. As a result, some borrowers were unable to repay their loans with the digital assets they held on Poloniex.
Also, the company said that as long as borrowers do not repay the specified cost, their accounts will be frozen. The very same stock exchange promised creditors to return their funds as soon as she manages to pay damages.
Lenders impacted will see the reduction in their accounts when they next log in.
To avoid such losses in the future, the exchange will remove the assets of BTS, CLAM, FCT and MAID from the marginal section. In addition, additional measures will be introduced to monitor risks when trading with borrowed funds, as well as measures to prevent strong price slippage and excessive concentration of marginal positions.
