How well should you know each other, on a personal level, to be co-founders?

"How do you tell whether there's a path out of an idea? How do you tell whether something is the germ of a giant company, or just a niche product? Often you can't.... sometimes I can see a path that's not immediately obvious; that's one of our specialties at YC."

=> Are there good alternatives to YC (a privilege not everyone can get), to get a 2nd-opinion validation of whether a startup idea is a path to a bigger one?

One of the biggest argument against BitCoins is it's lack of real-world utility. One of the way to bridge that is to provide a BitCoin-denominated card that can be used anywhere in real-world. (Probably prepaid or tied to a wallet for direct-debit, BTC-Credit would be quite disastrous i imagine)

Personally, I have a bunch of BitCoins, and I'd gladly use them to pay for my starbucks, esp on a day where the BTC/USD is high.

I would also like to carry this same card and use it worldwide if it can help me avoid the exorbitant FX spread my current USD card charges me.

But I wonder - if a BTC-denominated card is possible, are there bigger / more important use cases than that? What are the perils of a company trying to issue such a card? (FX risk? Regulations?)
