Under this standard, almost every cryptocurrency, including Ethereum and Doge, are securities.
I can see putting Ethereum in there, pre-sale, promises, and a ton of other things. Doge was started as a joke and never made any promises other then 'much coin'
But, and this is just me saying this just an opinion, they did a lot of things in terms of marketing, promotion and what not that made them a target.
There are a lot of other projects out there that are still around and not being bothered.
I don't want to say just another shitcoin scam, but this one got the eyes of the government on it. But, I can't think of any other way to put it.
Just my opinion.
