ChainCatcher message, Bloomberg ETF senior analyst Eric Balchunas posted on platform X that since the listing of the Bitcoin ETF, its volatility has significantly decreased. The 90-day rolling volatility has dropped below 40 for the first time, while it was above 60 when the ETF was listed. For comparison, combined with data from GLD, Bitcoin's volatility is now less than twice that of gold, whereas it was previously over three times.
