Q5: There is no selling of BTSX. All BTSX were initially allocated to PTS/AGS owners. There are some "unclaimed" - meaning they belong to someone but that someone hasn't transferred it yet. You can see the amount of unclaimed BTSX at www.bitsharesblocks.com (also there is a lot of useful info there)
Q8a: All unspent outputs that voted when they were last moved.
Q5: Interesting, I don't recall ever seeing this mentioned, is it in the wiki somewhere? I looked at the bitsharesblocks.com site which lists a
total supply of 1,999,902,838 and
unclaimed of 662,319,002. The difference is 1,337,583,836. Why is the total supply such an odd number?
I'm also puzzled by your statements "There is no selling of BTSX" & "All BTSX were initially allocated to PTS/AGS owners". What exactly do you mean? I can obviously "sell" or transfer any BTSX I have in my wallet.
Are you saying that if I obtained my BTSX from an exchange the exchange obtained them from one or more of the original investors?
This uncovers yet another gap in my understanding, that being how BTSX (or any type of blockchain "coin|share|note|thingy..." are created in the first place. Are you saying the genesis block "defines" the total number of outstanding shares and who owns them, and in the case of BTSX the genesis block lists all of the account keys for the PTS and AGS investors that existed when the genesis block started the BTSX blockchain? But the code is what allows for diluting, which just means increasing the maximum niumber of shates|coins|etc, right?
If a "block" is a group of transactions, what transactions make up the genesis block if it is purely a definition of the total pool of BTSX and the account keys of the owners of the BTSX in that pool?
Q8a: what ndo you mean by "unspent outputs"?
And
