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.
Everyone with money is not an investor nor an entrepreneur.. Your post was not very smart/nor helpful in my opinion.
Its like telling someone who drinks to stop drinking and start a vodka company..
Well, that comparisson is not really accurate. If he had 340k$ in that site than he is investor, we can't disprove that. By having such a big investment in site which is owned by ''we-don't-know-who", he made it really risky.
And i have already write that i didn't intend to be helpful in a way : oh i'm sorry, do you feel better now? not really, right?
I might sound like advertising, but with such an ammount (or even only 10% of it) he could make his own site, and take full controll of his investment, which means he knows all the risks and he can deal with them. Now someone took his 340k$ and he is blaming them, of course, try giving 340k$ to random guy on street and tell him that you will be back on the same spot in 1 year time waiting for money. What do you expect, to be honest?
