Isn´t everything effectively controlled by a group? At least by the users, even if there is no "leadership" or "company" behind it.
But the securities law definitions seem to require that the group has managerial control in order to classify the shares of the investment to be "investment securities".
But if you bought tokens in a game, you wouldn't be taking the pronouncements of the users of the game as promises for the future value of your tokens. The users are not in control of the management of the product (its protocol, compiled code, marketing, planning/implementing hard forks, etc). Crypto-coins are like a virtual game and the value is what the users say it is, so isn't a currency unless the users treat it as such.
Thus as I read the way the "investment securities" are typically defined by the courts and law (at least what I could find quickly), it appears the test is whether there is a controlling group
MANAGING the product that drives the value of the investment shares.
The users are not managing the coin. They often disagree with each other and have no consistent managerial organization. They are just using it within the confines of the protocol.
Only the developers truly have the influence to alter the protocol and have it widely adopted. So in my mind the test is whether the developers are acting like an organized controlling manager of the coin. A lead developer could be offering updated code for improvements to the coin and still not really be in control, if others are also doing so more or less uncontrolled by that lead developer and the nodes in the system are not dictated to or controlled by one managerial group as to which code they choose to run on their node. But if these developers have joined together in a coordinated group that is managing the coin and the users depending on the pronouncements and website of this controlling group for the official coin gospel, then I say it falls dangerously close to being classified as an "investment security" and especially if coins were sold to investors with the proceeds going to that managing, controlling group, and even more especially if there is ongoing revenue stream being taken from the coin and given to that managing, controlling group.
The stated reason that securities regulation exists is essentially to protect naive investors from incomplete, incorrect, and fraudulent disclosure by the managers of the investment. Thus if there are no managers, then there is nothing to protect the users from. How could the government regulate a protocol that no one is control of? Instead they can only regulate those who manage investments and those who facilitate exchanging shares in them.
Bitshares and Dash appear to me to be trying to escape the concept of "control" by passing the control off to masternodes and delegates, but in essence if you own most of the coins (or have influence over or confluence with those who do, because of your ability to control which developments get adopted), then you control these masternodes and delegates. So this appears to maybe be an obfuscation of their controlling and managerial role. They appear to be trying to sidestep the securities law, but I think they may fail. They are also US citizens, so I would not want to be doing what they are doing (I am also a US citizen).
Btw, I thought Monero was probably very safely distant from this problem until you told me they automatically manage the changing of the protocol every 6 months. That is a managerial role by a consistent controlling group. That would concern me if I were them. But I am very paranoid, maybe too much so.
Feel free to change your vote if I have changed your opinion with my post.
Edit: my opinion is that if there are funds supplied to develop a product and the managerial control is given up after delivering the product, then the product (and its tokens) are not "investment securities". So in my interpretation, a crowdfunded development of a coin that is then turned over to the community to run autonomously without ongoing managerial control of the developer or any controlling group, would thus not cause its coins to be "investment securities". But I am not attorney so consult your own legal advisor and I want to read what others think.
