Regarding Bitcoin's second layer, I have been watching it recently. Most of them are here to make money, and there are many big names involved. I am very optimistic about BTC's second layer, because BTC, as digital gold, has the greatest consensus and is the cornerstone of the industry. BTC has built the ecosystem in less than a year, which is what ETH did in nearly ten years. In the next six months, the BTC ecosystem will definitely explode. I think an excellent BTC second layer must adopt the POW mechanism and must be related to the first layer. It must be an extension of the first layer, rather than just a shell and call it a second layer. Recently, many people are optimistic about CKB, which I think is not bad, but from a technical point of view, I still very much recognize WVC. At present, some second layers are being released. The BTC ecosystem is about to usher in a big explosion, which will further promote the continued fermentation of the bull market, and at the same time push the development of web3 to a faster and healthier track.
