I find it fucking amazing, time and time and time again CloudMining companies like LTCGear pop up, and run. It's all a ponzi, its all it ever was...
Use your fucking brains.

I lost 680 KHs
You lost Bitcoin not 680KHs, they never had mining rigs.. You purchased a statistic on a screen, your past payments were funded by new 'investors', eventually like always the output is more than the input and they have no choice but to;
1. Blame it on hackers.
2. Claim the site was hacked.
3. Straight up disband and run.
