Side 1 is easy: The Biden administration wants to tax crypto to fund an infrastructure bill.
Incorrect. The estimated crypto tax revenues would account for about 2% of the spending in this bill.
Side 2 is easy: crypto investors think this will cripple growth.
It's not the tax which will cripple growth, it's the definition of miners, nodes, and developers as "brokers".
Side 3: Some senators want an amendment that limits the authority of the executive over crypto.
No, they want to clarify the language so that only actual brokers are classified as brokers.
Side 4: 2 senators propose a compromise, that exempts some crypto actors from regulation, seen as too few exemptions by Side 3 and too many by Side 1.
The proposed amendment didn't exempt them from regulation, but simply define broker properly.
Your video and transcript is badly inaccurate.
And if this bill passes, which it looks like it will, it's going to force the EU and others to change the way they view crypto dealings with individuals/p2p.
There might be a small sliver of hope for other countries. If this bill does pass unchanged, and forces miners, nodes, developers, indeed the entire cryptocurrency industry out of the US, then other developed nations will see a big boost to their own industries, along with the growth, profit and taxable revenue that this brings. They might decide it is in their best interests to legislate more cautiously/cleverly, and attract as much of this their country as possible. Imagine the advantage, for example, if one country had attracted the majority of early internet developers. They may view bitcoin and cryptocurrency in the same way.
