Devils advocate:

The SECs core job is to protect investors and assure orderly markets. But it is not clear that buying a crypto asset IS an investment and one job of markets is to take money away from people who make dumb decisions (like buying a crypto "asset" only because Coinbase listed it). So stopping this doesn't actually fit their mandate any more than stopping people betting on sports or buying lottery tickets does.

And that's without getting into the other points people have listed:

* the SEC is toothless * FX isn't a regulated market, you absolutely CAN use "insider" info to trade Euros, USD etc. * its technically AND legally hard to prove insider trading in Crypto (and elsewhere) * if they did, and Coinbase etc moved their operations to unregulated destinations would that actually make anyone safer?
