Since there was no ICO, the odds of any of the above being a security token seem pretty low to me (especially SP and SBD), though it would be better to hear from them (the SEC) directly.
Resteemed to get some discussion going and possibly get some input from Steemit,Inc.
I am no expert and can be wrong here but I think it is not only about ICO. If a coin generates income (e.g staked and lent SP) than that need to be registered with the SEC as well? An official statement from Steemit.Inc would certainly help.
Yes that can be part of it, though there does seem to be some grey area because that "income" is more cryptocurrency (as opposed to fiat money) and some of it is locked up for 13 weeks (SP). There are arguments that both support and refute the above as security tokens when using/applying the Howey Test. It would be great to have Steemit,Inc chime in.
Bitcoin and Ethereum have both been deemed not securities and Ethereum is moving to POS as well...
