The claim, plainly

Between 2017 and 2020, a massive amount of Bitcoin network hashing power shifted from China to North America.

Assessment

Data from the Cambridge Centre for Alternative Finance (CCAF) and CoinShares show that no massive shift of Bitcoin hashrate from China to North America had occurred by April 2020. In September 2019, China accounted for approximately 75.5% of global hashrate while the United States accounted for 4.1%. By April 2020, China still retained overwhelming dominance at 65.1%, while the United States had only risen to 7.2%. The massive migration of hashrate to North America (where the US share reached 35.4% and China dropped to 0%) did not occur until mid-2021 following China's State Council mining ban.

CCAF data indicates China held 75.5% of global Bitcoin hashrate in September 2019 and 65.1% in April 2020.
CCAF data shows the US share was only 4.1% in September 2019 and 7.2% in April 2020.
CoinShares reported in December 2019 that Chinese miners controlled 66% of global hashrate, reflecting continued concentration rather than an overseas migration prior to the mid-2021 mining ban.
