Wu said that he learned that the inauguration ceremony of President Nayib Bukele was held at the Gerardo Barrios Square in El Salvador, starting his second term. Five years ago today, Nayib Bukele was sworn in as the President of El Salvador, becoming the first Bitcoin president. On September 7, 2021, Bitcoin officially became the legal tender in El Salvador. On November 18, 2022, El Salvador began a daily fixed investment of 1 Bitcoin. Earlier in March, Nayib Bukele stated that he had deposited the daily fixed investment of 1 Bitcoin into a cold wallet, and this "daily fixed investment" situation will continue until the day when Bitcoin can no longer be purchased with legal currency.
