This would be /very/ hard to coordinate with Bittrex. However, how would you feel about the total coin supply and mining reward being changed to match the amount of coins sold?
For instance, the 10 coin block rewards are currently assuming we sell all Envycoin's in ICO. If we only sold half, we could halve this reward so that really, you'd own that large of a stake in the supply. So, if you buy 1% of the ICO coins, you'd own 0.5% of the total supply (after it's mined out, in 10 years) regardless of how many coins are sold
Yes, that would be an improvement. But, I didn't bring this up initially as I am not here to FUD your coin (in fact, I am very interested in it), but why is there mining at all? Why aren't we using 100% of the BTC invested toward the plan. Aren't the miners just diluting everyone's share of the income?
As far as it being "hard to coordinate with Bittrex", I doubt that, only because I know for a fact that Poloniex has run ICO's using that method. All that has to be done is that you (or they) calculate the proper pro rata share at the end of the ICO and they add that to the wallet. They have all of the wallets (and coins!), so it can't be that hard.
Like I said, I am not here to disparage the coin, and I may get some anyway, but I am confused on the details. Isn't at least part of the appeal that if we all chip in to the coin, we will get a better hashrate deal than if one did it on their own? And on top of that we will have a nice coin to boot that might rise in value, get added features, etc.?
