OMG i don't have words to say than, how in the world can you trust someone 340k$ ? I know i'm not helping to lower your pain, but look it that way:you learned something in investment, which you could lear much easier.
Belive me you could invest those 340k$ in your own page and you would be making at least 20% per month. You can consider this as a tip for the future.
I'm really sorry, but i'm realist.
I didn't "invest" 340k with them. I merely deposited significantly smaller amounts of bitcoins with them (roughly $6,700) worth each time. most times I lost them, but the last time I won, and won big. from $35,000 up to $340,000. i never "trusted" them with that much money and never gave them $340,000.
I tried to cash out many, many times along the way, but was never allowed to. in all reality the most of my money i ever trusted them with was roughly $6,700 worth of my bitcoins at any given time. along the way i gave them a lot more than that total (maybe 250BTC, worth more at the time than they are now) but always as much smaller deposits which i kept losing.
