It is all based on risk vs return. There has been a lot of risk that the company won't make it another year. Recently, Foote has done things that indicate that the company intends to be around - ie. debt elimination, filing for patents, reduced dead weight, selling it's financial division for monthly revenue... It isn't a scam company like much of the OTC is. Doesn't mean that the company won't fail, but the risk has been greatly reduced when they eliminated roughly $50mil in debt. Further, Foote indicated that this tech is his dream, but if it comes down to it, he would allow the company to be acquired for the benefit of the shareholders if he can't make it work.
Now we are looking at a company that needs to make $230k/month at current expense levels to start making money. If they do, the stock price would jump exponentially. Throwing in $100k to potentially make some real money may not be a bad deal.
