I agree with Accountant, the lack of financial reporting standards is scary. But I would interject that most of the people involved aren't aware of the Financial Accounting Standards Board (FASB), or Statements of Financial Accounting Standards (SFAS). While I am not a CPA, I have had several years of training and education in accounting. If more of these people seeking funding through bitcoin securities had a good set of honest books, and the security exchanges enforced some sort of standard reporting it could be taken a lot more seriously. I have tried to read some of the "prospectus" some of the companies listed on the exchanges posted and it was terrible.
While I understand the point of bitcoin is a decentralized monetary solution, financial reporting (even though all bitcoin transactions are publicly traceable) is important for a viable and serious securities market.
My eventual aim is have a securities rating service. Much like services offered by Moody's and S&P. I am also very interested in equity research done by investment banks. I feel that it is something that will benefit both the investors and miners.
