Thing I don't understand is, if you do want to buy into these companies, then it is your right to do so, but if they are obviously building a business, then you run the risk of having to wait to see real, concrete progress. If you think that these are not a wise investment and only here for the companies to make money off investors, then it would make sense to NOT buy their stock. It's always left to investors to do their DD. ANY investment into a company is a risk.
