For question of whether SEC has jurisdiction over cryptos, there is something called "Howey Test" for anyone that is unaware of:

Under the Howey Test, a transaction qualifies as a security if it involves the following four elements:

- An investment of money

- In a common enterprise

- A reasonable expectation of profit

- Derived from the efforts of others

To be considered a security, a transaction must meet all four prongs of the Howey Test.
