Maybe you should just set the purchase price at 5000 sats or more, and extend the ipo to a month. People might be willing to spend more bitcoin to get a guaranteed amount of warp, instead of it being a wild chance that you could end up with 10,000 + or under 1 warp
Specifically regarding this comment, if at the end of the sale, distribution looks bizarre, uneven or unfair - all percentage wise among the full list of investors, it wouldn't make sense to complete the project. A good environment is needed to hit a market, fair distribution is essential. Maybe 10 days is a bit too short, let's see, but I like the fact that I don't choose the price per WARP, but everyone else out there do.
release wallet v.2 , set individual warp price at 5000 sats , and set a a minimum buy-in of 0.1 btc + reserve a bit of the warp for yourself for future bounties etc, so 2000 warp per 0.1 btc
for example ethereum sold 1000 ether for 1 btc & raising the threshold of the minimum buyin over time, worked well for them, although it did take some time for the price to rise above $1 (price of bitcoin at the time was roughly $1000)
just some food for thought
