The arrangement had always been a "group buy" as the SUBJECT of this thread suggests. All investors own all machines equally sharing all the risk between everyone.
I can not imagine the extra work load determining who's is what and when and how much.
It's a GROUP BUY.
I dont want to take a side because i think both views have advantages but it was planned as a group buy to buy one avalon machine. Then another one. At least iam thought all the time i put my money into to buy the one machine.
Maybe in future groupbuys this has to be specified more exactly. Im ok with having a part of all machines because it spreads the risk in case a machine is broken or something.
