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.

Selling now after investing in ICO is waste. I'm gonna hold even if it crashes to 0.
