The Bitcoin Lightning network has grown by over 23% in the past three months, and El Salvador has included BTC in terms of profitability, or that's the main reason.

Golden Financial reports that the number of Bitcoin Lightning network nodes created on the Bitcoin mainnet increased by 23.13% between September 3 and December 3, 2021 and currently exceeds 31,000. So far, the Bitcoin Lightning network has experienced two major growth opportunities. The first phase of growth took place in January 2019, when Twitter users, including the former CEO of Twitter, started working to pay friends called “Lightning Torch”. Joining Jack Dorsey and LinkedIn co-founder Reed Hoffman and other dignitaries, the second phase of development will take place in 2021 when El Salvador joins BTC as fiat and announces the mass adoption of strike bag money. Twitter has also announced its support. All six BTC protocols also support Lightning Network node development.
