That is why you probably should wait as long as you can to release the whitepaper (or maybe a short version first then the full paper when it is needed.)
the plan is to finish the paper first, that'd be safe and successful to my estimation, but, if buyers will repeat this request from me due to e.g. fear of competition (i.e. if more people agree with you), i can postpone publications by putting time into code
(i'll reply later with little more detail about tezos)
