Brian, thank you for that 2-part question. Much appreciate it. It seemed like a little more parts than 2, but that's okay. So let me try to address it. And I'll ask my team to join in where I think they're all vigorously taking some notes on some of your points. So Julie and Tim McCourt will both join in as well and maybe others. But let me say a couple of things. One, in my prepared remarks, I referenced 90,000 new users for the first time, which I think is something that -- I've been here a long time. It's really not -- it's very unprecedented to see that type of growth. I think it's up 56% is what I referenced. So to me, that is very, very exciting from the retail perspective and the growth. I don't believe that's going away. And I've said this to you, Brian, and the rest of the analysts and others that cover us, these people want access to markets, and we're going to make certain we give it to them. And I'm very, very optimistic about this segment. I'm never trying to predict the direction of markets, so I will never do that. But I will say that people have access to markets they never had before. And I don't see that slowing down. I think it only accelerates for many more years to come as people start to participate in different markets. As far as the different asset classes, I think, Brian, was part of your question. Do they go from trading crypto to maybe gold or other asset classes here at CME? I think as people evolve -- people always seem to evolve into different asset classes. And as you know, Brian, very well, when one asset class seems to be getting a lot of attention, a lot of people follow it. Right now, we're seeing a lot of people follow the crypto. We can talk about some of the legislation that has passed and reasons why they're following crypto. So we've seen a massive uptick in the crypto markets as has others. So not a surprise. We saw a lot of people attracted to gold when gold hit $3,500 an ounce just a few months back. So that is not a surprise. When crude oil traded up to $125 a barrel, you see a lot of people -- this was several years ago, going after that trade. So I think that there is not any one particular asset class. That's the beauty of CME. We have multiple different asset classes that people will follow, but they also follow things that are -- that have attention to them at that given moment in time. And they have the ability to do that now where maybe 10, 20 years ago, they did not. So they can move from asset class to asset class relatively quickly and seamlessly. That was one of your questions. So I think they participate in all of our asset classes, depending on what's going on fundamentally. Your other question was around crypto, I believe, as it relates to will we continue to accelerate our entry into crypto. From my standpoint, right now, we are hardly a first-mover in crypto. I think that we are a fast follower, to say the least, and we have a lot to offer in our crypto franchise. I think there's a lot of people that like to have the regulated platform on crypto, and it gives them confidence. I think that's one of the reasons you've seen massive growth in people that are more mainstream in today's financial system trading it because they're using CME's reference prices to do that and are based off of our futures contracts. So we will continue to participate in that venue. As far as perpetuals go, Brian, I think is one of your other questions. I thought I heard you say, perpetuals are something that are illegal in the United States of America. They do have them in Europe. So the question is we will have to wait and see how the regulations shake out on perpetuals. There are certain products that are not conducive to perpetuals. Mainly deliverable products are not conducive to perpetuals. So cash settled maybe more so, such as the crypto markets could be more of a perpetual-type contract, but there are many products that just would not be efficient as a perpetual as it relates to risk management that are deliverable. So when you look at energy, you look at rates, you look at all these products that are physically delivered and people are counting on that delivery mechanism in order to manage the risk to take delivery or make delivery, perpetuals do not work. So I think it will go back and forth, and we'll see how the regs shake out. That's about what I heard. Maybe the team wants to pick up more, Julie or...
