PANews June 4 news, according to CoinDesk reports, Sygnum Bank's report indicates that the circulating supply of Bitcoin has decreased by 30% over the past 18 months, which may lead to increased price volatility. ETF inflows and the increasing interest of various governments in Bitcoin reserves have intensified the possibility of a 'demand shock' — more buyers with fewer tradable tokens. Since the end of 2023, over 1 million BTC have flowed out of exchanges, primarily due to ETF and institutional accumulation. In addition, the turmoil in U.S. Treasury bonds and the weakening of the dollar are reinforcing Bitcoin's safe-haven properties. Geopolitically, three U.S. states have passed Bitcoin reserve bills, and politicians in Pakistan and the UK are also considering including BTC in official reserves.
