A decline of about 2.2% from current levels would push Bitcoin to $81,722, which Bloomberg ETF analyst James Seyffart estimated on September 21 as the average Bitcoin ETF holder's cost basis. Seyffart had noted that the recent rally had put these holders back in profit. The price action around this level will be closely watched, especially with the release of US inflation data on Wednesday. Separately, a September 9 Glassnode report placed another ETF-complex break-even point near $86,000, while analyst Axel Adler Jr. calculated Bitcoin's 365-day moving average at $80,500 on September 22.
