Anyone can start one, but the SCSL license on the BitShares code will require honoring PTS/AGS holders
I better hold on to my PTS then
One more question - if there are separate blockchains for each group/type of assets, do I have a separate balance for each of them? If I make a profitable trade in one chain, will I then have to trade that profit on an exchange if I want to switch to a different chain?
Btw I think Bitshares could be a game changer because it will allow people to get around so many national restrictions. For example the Chinese have restrictions on investing in overseas assets, whilst the US has restrictions on CFD trading. Bitshares just allows everyone to get around all of this. Anonymous decentralized trading on any asset in the world - this could be as big as bitcoin itself.
