Donating to Angelshares generates money and strengthens its support system.
Re-opening Founders opportunity would only compensate those who did not want to take the risk at an earlier stage of the development (now that they can see the alpha Keyhotee for instance).
Wouldn't we all like to be able to invest in startups at an earlier stage
of their development (once further development progress can be seen). We would each and everyone of us be billionaires with such perfect hindsight.
I am very mcuh against OP's proposal. He can invest now in Angelshares which are still at a very early stage (and he can then sell his investment to latecomers well below the market if he so chooses
).
