If I purchase a passthrough share, who's share am I actually purchasing? (or essentially, which "real" share is the dividend coming from?)
One one hand I thought it would be purchasing from burnside - he is running the exchange, and I imagined he couldn't "sell" anything he doesn't have the authority to "own", hence I figured he had a large portion and we were essentially trading out of his pool. This would mean on btct.co we're dividing up the 350 shares burnside owns personally? If 50 share owners converted to "real" shares does this mean the pool is ever shrinking and we would only now be dividing up 300 shares?
On the other hand a few advantages mentioned was being traded in large volumes easily, so it makes me think it can't be this pool of burnsides shares. Hence how does an exchange have the authority to trade in them, and how do they receive the divided to pass through? Does the exchange have it own separate pool of shares? Again how is the pool 'replenished' from conversions if the public (exchange included here?) can't buy shares from ASICMINER?
Again, sorry for the basic questions. I'm sure it's a similar set up in most share markets but I've never really been exposed much to it and I'm really interested in how it's working.
Thanks
That's a good question. It works like this:
I hold (but do not own) ~5800 shares of ASICMINER with Friedcat. All of these shares trade on the exchange. When Friedcat issues divs, my wallet gets divs for all 5800 shares.
On the exchange, I hold (and own) ~350 shares of ASICMINER-PT. Other people hold the rest. When I pay divs that have come in from Friedcat, they are distributed to everyone's btct.co accounts based on how many ASICMINER-PT shares they have.
And the important part: Every ASICMINER-PT share is backed by exactly one ASICMINER share. So the number available on the market is exactly the number I am holding directly with Friedcat.
Hope that helps!
