The snapshot taken on Feb 28th was for Bitshares X so anyone who invested in AGS up until that date will get their stake.
I have to disagree about it not being well thought out. I would argue that this has been thought out far more than any other crypto-currency. Many of the results have been from a deeper inspection of what is actually going on.
For example - I don't read here as much as I used to, but I recently read a thread with complaining about a TV talking head suggesting making BTC be constantly inflationary. Everyone starts comparing it to doge. I'm pretty sure I'll be dead and long forgotten by the time Bitcoin stops inflating the money supply. No one even stops to examine the underlying premise - that a currency needs inflation to remain secure.
