Now that there is no business, the value of the assets and liabilities remaining after bankruptcy is all that matters now. So, that calls for a spreadsheet.
Actually, a spreadsheet WOULD have helped 3 years ago, by creating one that showed the debt, interest, and cash burn, which admittedly would be more complex that the current bankruptcy spreadsheet.
As far investing in a "wonderful product", that is really only one of MANY important criteria for investing. I can't say this loud enough, INVESTING IN A COMPANY MAINLY BECAUSE YOU THINK IT HAS A "GREAT PRODUCT" IS NOT ENOUGH TO MAKE IT A SMART INVESTMENT!!!!
Even though it should, I am willing to be that even now, many pink sheet shareholders do not realize this, even here, despite this bankruptcy after having supposedly great products!
You CAN'T invest in a technology, you buy stock in a COMPANY, not a technology!
