Please, stop doing that. You won't get anywhere by saying all other major projects that occupy the same space as Bitcoin are scams. You're not helping bitcoin by doing that. You're not convincing anyone that bitcoin isn't crypto; it's the first crypto, and frankly it's been superseded by other FOSS projects like Monero and Ethereum in various places. Either all of crypto is a scam, or we have to take things on a case-by-case basis. By using this Bitcoin-only logic, you're just turning more people over to the former position. Many of the best innovators in the scene have been working on anything but Bitcoin for a long time.
