They've all been staked, and all the coins are with the market maker. The market maker can freely dump the price. You originally bought 10,000 coins for 1.6U, which had a market value of 16,000U. After staking for a few months, it turned into 13,000 coins. Having gained a few thousand coins, you were very happy and were just about to sell to make a profit when the market maker crashed the price down to 0.2U, resulting in a market value of 2,600U! Damn! You've fallen into the trap $USUAL .
