Hi @qsyal
Thank @crypto.piotr because you invited me to this post.

I have been reading many articles on the Halving. However I haven't met a complete one yet !!

It turns out that there is a secret message embedded in block 629,999, one block ahead of the Halving block (630,000). The message reminds the public of hidden messages in the first block ( genesis block ), the 0th block of Bitcoin on January 3, 2009 ago.

The message pinned in block 629,999 was: "NYTimes 09 / Apr / 2020 With $ 2.3T Injection, Fed's Plan Far Exceeds 2008 Rescue" . The message refers to news in The New York Times on April 9, 2020, about the plan to roll out additional funds by the Fed (Central Bank of the United States) to save the economy, the amount of which exceeded the crisis of 2008.

The message reminded the public of the message in Genesis Block in 2009 ago . At that time the message pinned by the creator of Bitcoin, Satoshi Nakamoto was: "The Times 03 / Jan / 2009 Chancellor on brink of the second bailout for banks" .

In other words, "from 12 May 2020 to the next 210,000 blocks (equivalent to 4 years), the number of Bitcoin is increasingly scarce, from 1800 BTC per day to only 900 BTC per day."
