I voted Grapefruit but to be serious for a second I think any kind of mining centric company is going to automatically go bankrupt sooner or later, it's fine if you want to do that as a side thing but I've decided I refuse to have anything to do with it, the numbers just don't ever add up even for the reasonably honest companies, I'm talking about both the ASIC companies as well as the ones that are essentially renting out hash power.

Put your money in somebody that has a long term plan and wants to make a real business, just dumping it all in hashpower is short sighted and foolish, especially with the way difficulty works with these currencies.

Edit: Just saw the new butterfly labs 'mining' card and I'm in hysterics, it looks like a regular high end Radeon card with a butterfly labs logo on it
