My reading of USA law is that if CK coins were obtained at any time by USA citizens or residents as investment securities from some controlling entity, then plausibly the SEC (if it has the cooperation of the other nations) can prosecute the controlling entity and take actions to shut down the coin, such as declare running the protocol to trade the illegally produced securities an illegal act.

One of my alternative theories is that Bitcoin was planted by the DEEP STATE to impel the nations of the world to join together to fight the lawlessness and deregulation that Bitcoin enables.

The only way I see to avoid the coins being classified as an investment security is to sell a product (the coins, source code, and initial autonomously running network) as a contract job and do not retain any control after that sale.

I haven't studied how you are distributing the CK coins in all cases, so I can't comment on whether I believe CK coins are tainted illegal or not under USA securities law. Also I would rather not make any such legal comment about any altcoin.

Usual disclaimers apply that I am not an attorney nor a legal adviser. Every reader should consult their own.
