Bitcoin fell about 1.5% to just above $84,200 in Asian morning hours on Wednesday, briefly breaking below the $84,000 level that FxPro analysts flagged as a key support. This comes as Brent crude oil rose almost 1% to about $101.50 a barrel due to increased Iranian attacks on tankers in the Strait of Hormuz. The dollar strengthened against other Group-of-10 currencies, and the 10-year Treasury yield climbed three basis points to 5.31%.
