you lost that money yourself, not because of the market. The way it fluctuated, there is very little excuse not to have made at least some profit.
Of a 1BTC investment on Bittrex, I currently have 0.74 BTC and around 1000 MCO I'm holding. that means that even at the current price I'm still at an overall gain (and holding below .0008 was a choice).
Sell at a loss, lose.
easy as pie.
