Too late for that - it's already through the Senate. And sure, politicians might not be completely dumb, but they are bought and paid for by banks and Wall Street, which, is has emerged, was likely the reason behind Senator Shelby objecting to every cryptocurrency amendment proposed in the Senate.

It has passed the Senate, and now it is headed to the House of Representatives. "Congress" refers to the entire legislature, both the Senate and the House together.

There are already some Representatives in the House talking about proposing new amendments to the cryptocurrency provisions. The House won't be back in session until the 23rd August, so you've got a little bit of time to contact your Representative and express you concerns: https://www.house.gov/representatives/find-your-representative
