What Janey Yallen was trying to say is that there needs to be a lot more surveillance in the crypto world and not let it be so much anonymous, otherwise not in a financial situation that would impact on us. Meaning, you could buy and sell crypto all you want, you could profit from it as much as you can and by all means make the most profit from other nations and bring their money to USA, Janet would be very happy about it, but let them know while doing that, tell them how much you bought and sold and whatever and in the end you would be capable of living your life like the old days as long as you let them know.

The thing they are against is the privacy part of bitcoin and since we are not dealing with XMR here, bitcoin is not THAT private neither, people can trace addresses and transactions and figure out where you took your money, so it is not really that interesting request neither.
