 Anonymous asks, what other crypto-assets or technologies interest you besides Bitcoin and Ethereum? I'm interested in a number of different technologies. I'm particularly interested in the privacy-related technologies, because I think privacy is a very important thing. In those blockchains that are pioneering and testing various forms of privacy, anonymity, etc., including Monero, Zcash, etc. I'm interested in some of the other technologies, but not enough to mention any more, that are doing some kind of exploration of different possibilities, specifically resource-sharing blockchains where you can buy computer, storage, or network bandwidth, or rent those resources. Rent out those resources if you have access, and rent those resources if you need them, using some kind of cryptocurrency or token to do the transaction and some kind of blockchain to record the resources. Valentin asks, what are your thoughts on Litecoin? Do you see it as the silver to Bitcoin's gold? I think Litecoin has found a very interesting niche, which is moving faster and with much more rapid development in a very particular area, which is basically Bitcoin only faster. So far, Litecoin has managed to deliver on the promise of silver to Bitcoin's gold, being the first to do Segwit, a number of the softworks, atomic cross-chain swaps, or Lightning network with other currencies. All of those things indicate that it's able to move pretty fast, of course, by taking a lot of the innovation from Bitcoin and following the core roadmap pretty closely, too. That's a good place to be. That's not investment advice. That just means it's interesting to me to watch what happens in that market as a test of new functions that are coming in. As a technology, it's interesting. I think Charlie's done a pretty good job steering that. Again, I think it's a different niche from Bitcoin's. Anonymous asks, do privacy-focused altcoins like Monero have a future in light of the second-layer innovations coming to Bitcoin? Yes, I think they do have a future. The second-layer innovations do increase privacy, but the base layer, and even the second layer, doesn't have some of the privacy capabilities that you see in things like Monero and Zcash. I would like to see those innovations implemented in Bitcoin, in the base layer, to increase Bitcoin's own privacy, but for a blockchain that's focused on privacy and continuously innovating with that one focus only, they have an advantage. They can move faster, they can implement new features, they can cherry-pick the things that are invented elsewhere and use them within their own blockchain. As long as they continue delivering quality code that's well-maintained and has few security bugs, they absolutely do have a future. That type of specialization, that type of differentiation, the kind of thing that Monero and Zcash are doing, I think is valuable. It's not likely to be eclipsed by Bitcoin anytime soon, so it has a smaller niche market. At the same time, it's not going to suddenly replace Bitcoin. I think that's not realistic. But there's room, this is a very large environment. There are niches available for every single type of blockchain. Each blockchain gets to explore its environmental niche and expand within that environmental niche. Bitcoin is not occupying the privacy-conscious environment niche for cryptocurrencies. It's occupying the robust, high-value, secure transaction, and very immutable niche. How important is that niche? That's a whole lot of discussion, but that's the niche it's occupying. Monero and Zcash are really expanding the niche for privacy-focused blockchains. I think that's very interesting. I think it's mistaken to really look at these things as necessarily competing head-to-head. As I talked about in my talk, The Lion and the Shark, I think there's plenty of room for multiple different Apex systems that are the best at what they do, and yet are not in direct competition with each other. I'm very interested in all of them, and I try to keep track of as many as possible, although it's not easy. Anonymous says, would you agree that hypothetical attempts at bootstrapping a completely new value token are now virtually guaranteed to fail? No, I wouldn't agree. In fact, I thought that in 2014, after the altcoin mess in 2014, and the initial coin offerings and all of the altcoins that came out in 2013 and 2014, I thought, this market isn't going anywhere. Nothing is going to be interesting enough to compete with Bitcoin and produce an altcoin that could actually get some traction. Then Ethereum came out. Honestly, a number of others that I find somewhat interesting, that are differentiating sufficiently and doing things that can't necessarily be done on the same blockchain as Bitcoin. Yes, you can. The idea that there aren't other ideas out there that are just as good, I think that's naive.
