MyBitcoin is a Limited Liability Company, so the owner(s) is not personally responsible for the company's debts. This is a very good thing, because it allows entrepreneurs to start risky ventures without putting their entire lives on the line. If we didn't have limited liability entities, there would be a whole lot less innovation, a lot less wealth, and a lot fewer jobs.
One man's innovation is another man's fraud. A corporation is a legal person created by state statute that can be used as a fall guy, a servant, a good friend or a decoy,
the companys website boasts. A person you control
yet cannot be held accountable for its actions. Imagine the possibilities!
The whole situation with mybitcoin smells fishy. My instincts tell me that "Tom Williams" is a pirate. Captain Tom!
