...This would make the starting EXCH price about 1.77 BTC before management fees. If the price seems to be too high, then I'll just do a 10-1 split.
1.77 BTC not only seems too high, it is.
i'm sure here are many people who do not have enough amount to buy even 1 share...
and it could rise some liquidity considerations for others inclusive myself.
we have here not a NYSE... besides there is really no need to make a price of 1 share equally of some monster corp, such as Apple or Google or such

me thinks 1:10 of 1.77 BTC should be fine, imho

Okay, well thanks for the feedback. As a point of reference, BTC was about $850 when I started BDD in Jan '15. At .24 BTC per EXCH, that was about $204 per unit. Now, that would be about $412, so maybe you're right. 1TH is s nice round number, maybe I'll shoot for 250GH.
