The crypto market has become dull, with bitcoin (BTC), the world’s largest digital asset by market value, falling into the tightest price range in months amid persisting fears about the stability of regional banks in the United States and the country’s debt ceiling.In the seven days ending May 21, the range, or the difference between the high and low, was 3.4%. According to statistics recorded by analytics firm Glassnode, this is one of the tightest in the last three years and equivalent to the lacklustre trading observed at the start of the year, for a brief point last month, and in July 2020.
