According to Coinglass data, in the 12 "May" market movements of Bitcoin since 2013, 6 have closed up and 6 have closed down. The largest increase occurred in May 2019, with a monthly increase of 52.38%. The largest decrease occurred in May 2021, with a monthly decrease of 35.31%.

This May has too many uncertainties; personally, I remain bearish unless there is significant positive news.
