I'm pretty sure the US already made some regulations regarding bitcoins. The result was many US based bitcoin companies or exchanges were basically forced to go off shore. After that I practically stopped following the topic, as that also brought a lot more money into the scene and the regulations didn't affect me, even though i disagreed with it. As some said, the regulation can be inviting to future investors. I also agree that it defeats the purpose of decentralization, but maybe this is a learning experience for all of us, when you consider all the scamcoins and scam ICO's that have come and gone over the years that maybe 100% decentralization isn't always a good thing. Regardless, 100% regulation is an absolutely terrifying idea. I guess there has to be a happy medium, and I believe the technology of bitcoin will only allow for so much regulation. After all, it's decentralized. I still believe in decentralization, however back when I started, it felt like the wild wild west of the internet. Now it's gotten much better. I think regulation will only make it better, especially if and when over-regulation produces worse results where they'll be forced to backtrack on their decision. Regardless, it's going to be an interesting show moving forward. Has been since day 1.
