If we go for a pre-sale. It will be a Bitcoin only AGS style one. Only shorter, 30 to 60 days yes.
I think only 10% should go to pre-sale. 20% to pre-sale is too high.
Also at what price should the presale be? It has to be higher than what PTS and AGS paid for it otherwise it's at the expense of PTS and AGS. PTS and AGS was like the initial pre-sale. People donated and got shares.
If there is another round then the shares should be more expensive. But I don't see why this is necessary.
Do you have expenses that require both 10% to the foundation and then another 20%? Basically you're saying the foundation should get 30% up front? I'm skeptical of this plan because you haven't established where the money should go, why it is needed, and why you think Bitshares Music could raise enough money in a presale to have it be worth it.
Also the whole presale thing seems like a completely unnecessary ritual. If you just say 30% goes to the foundation then you can just sell that. I think the presale idea is bad.
