Very important question:

What happens if you receive much less than your 75 Btc goal?

I don't mind much the absence of an escrow, as I know that an escrow is no protection anyway when anybody can get a generic clone coin for a fraction of a Btc from a walletbuilders service -- it is always how hard and well the developer works in other ways that matters.

But no escrow will turn off other potential investors, so it is really unclear how much you will get.  I don't know that a whitepaper is strictly needed, but it helps show that a project has had serious effort already put into its details.

Second question:

If your plan is to launch the IPFS platform website on March 5th, when the ICO might last up until that exact day, then you apparently don't need ICO funds to do that initial part.

So, if that website launch date is realistic, why wouldn't you simply have the ICO extend several days beyond it, to get what might be far more funds after having more of a demonstration?  What if that made the difference between getting 15 Btc and getting 75 Btc?  I have seen some legitimate businesses be oddly careless in ICO planning, so it is not just you, but still I wonder.

I have not got around yet to completing other research like your post history and everything else I can find, but, by default, I don't have much else to evaluate or go on for your skills at business planning.

My gut feeling is that I don't think you are a scammer, but I wonder if you could get insufficient ICO funds and fail by accident.
