Unfortunately with the confidence in Bitcoin down and not sorted for any recovery yet, the chance of any of these being profitable is small.
Until or if, mainstream adaption of Bitcoin takes place there will be no market of any value for these.
Great ideas but without mainstream backing/input, great ideas is all they will be.
Careful with your so called IPO, donation money, as any US based entity could be taken out by the SEC for a multitude of legal breaches very easily
The holders of some of the funds are very much at risk because they are managing them with real ID's
Wouldn't take many complaints for failure to deliver the product from disgruntled donators/investors
I'm sure most guys putting money in are not expecting absolutely nothing in return but that may well be the case
caveat emptor and all that
