One interesting factor is the strategy SEC are using to label altcoins securities. Instead of going to for altcoins themselves, they are going for the exchanges facilitating trading instead. This effectively means that the altcoins can't defend themselves against the accusation (as this becomes the responsibility of exchanges if they chose it to do so). This is similar to the
SEC lawsuit against Kim Kardashian and Floyd Mayweather for shilling Ethereum Max. They never actually filed a lawsuit against the coin, but only the promoters. So it very much seems they are trying to same tactic here again, in order to get certain altcoins classified as securities by courts, without the founders/executives of altcoins being able to defend themselves against it. I realise that XRP is the exception to the rule, as they are defending themselves right now which is probably costing SEC a lot of money, hence they are likely trying to avoid directly creating lawsuits against other coins with lots of funds available.
Well attacking CEXes would be obviously most effective starting point, they would be basically exchanges buying and selling unregistered securites in the eyes of SEC.
And you can't really leave all this (declaring some altcoins are securities) to the shoulders of SEC. Many of these currencies has very questionable marketing tactic to begin with.
In sale phase of a token/coin, marketing itself can define if the token or coin is a security. Which is one of the reason when they are attacking the third parties providing the hype for tokens/coins. And i am guessing that most promoters got free hands on promoting and are promoting those assets illegally, hinting any growth in investment price is enough.
I am not sure what kind of place twitter is these days but at some point they needed to add more restrictive rules for promoting things like cryptocurrencies. Which most people didn't seem to follow, but i am guessing that was twitter's way of washing their hands so they won't get sued by allowing this.
