Good question, it does happen! I tell them that it's not what they think it is ;) To my knowledge, we never promote concepts like doing DeFi or non custodial magic. We just say that we use Lightning for instant trading, and that on LN Markets, you take less risk since you trade directly from your wallet and only leave custody of your funds when the position is open.. So it's not DeFi and I have doubts that any of DeFi is truly Decentralized.. However, what we want to build is non custodial financial products on top of Bitcoin. DLC could be an option, and we're happy to explore any other leads we can find!
