The Bitcoin (BTC) halving in 2021 you mentioned seems to be a bit of a mix-up in dates. Bitcoin halvings occur approximately every four years, and the most recent halvings before 2023 were in 2016 and 2020. The 2020 halving event occurred on May 11th. Here's a brief overview of BTC prices around the time of the 2020 halving:
Before the 2020 Halving: In the months leading up to the halving, Bitcoin prices were recovering from the March 2020 crash (due to the COVID-19 pandemic) and were on an upward trend. In early May 2020, just before the halving, Bitcoin was trading in the range of $8,000 to $10,000.After the 2020 Halving: Following the halving, Bitcoin's price continued to rise throughout the year. The cryptocurrency entered a bullish phase, breaking past previous resistance levels. By the end of 2020, Bitcoin had surpassed $20,000, and in early 2021, it continued its rally, reaching new all-time highs. It peaked at around $64,000 in April 2021, experienced a significant dip in the following months, and then surged again to a new all-time high above $68,000 in November 2021.
Keep in mind that Bitcoin's price is influenced by a wide range of factors beyond the halving, including market sentiment, regulatory news, and macroeconomic trends.
