The SEC won't succeed because there are powerful forces at play. It's not about Bitcoin, but rather crypto as a whole. There are a lot of investors with money placed on alternative blockchain networks. Crypto exchanges certainly won't give up without a good fight. I'd suggest Coinbase to team up with Binance just to take the SEC down.
SEC are fighting against a whole cryptocurrency industry so their chance to succeed is not too big. I am positive about strength of this industry to fight back so I believe that together we will win against SEC.
Coinbase, Binance are not the first and will not be the last centralized exchanges or cryptocurrency projects, companies are hunting by SEC. However they are very first entities to seriously fight back in history.
I know many altcoins are centralized, but there are a few hidden gems that are really worth our time and attention. I think the SEC doesn't understand the difference between a truly-decentralized cryptocurrency and a centralized one. If it did, it would've only classified centralized coins as securities. Congress did question Mr. Gensler a while back, so let's hope he is removed from office for the good of the crypto industry. Who knows if the US will reemerge as the leader of crypto/Blockchain in the future?
I agree that altcoins are very centralized but if decentralization or centralization is key for SEC to beat cryptocurrency projects, they did not succeed to use that weapon with Ripple $XRP.
If they can not win against Ripple that is a very classic centralized altcoin, they will not be able to win other big altcoin projects. Big altcoin projects like Ripple will have enough funds for lawsuits, lawyers and they will not easily to give up before a final whistle.
