Don't worry, soon they'll payout 1% of your investment and then maybe no more. If you then invest this 1% in a tradingbot you will make profit.
If you then wait for btc or bcc to go up 10x you'll have your initial GM investment back.

That's how I look at it, got over 10 btc invested in GM, but now consider them lost.

But hey, there's things like bitconnect and control finance etc...
