Long story short: an insurance company for Bitcoin-based services.
That idea is really good. You never can be 100% safe. And all the banks and other exchanges have similar insurance-institutions.
I hope you're sarcastic... that is the worst idea ever... BITCOIN INSURANCE SHOULD BE RELIANT ON THE PPL WHO HOLD VALUE IN BITCOIN!!! Meaning we need to have our own personal insurance, making sure its successful and nobody gets fucked over. More importantly making sure Bitcoin has value in being able to buy real products, such as organic food made from local farms, and being able to sustain these farms, as well as the internet which hold the bitcoins... you get the idea.
