PANews June 4 news, according to CoinDesk, Sygnum Bank reported that the 30% reduction in the circulating supply of Bitcoin in the past 18 months may lead to increased price volatility. The inflow of ETF funds and the interest of governments in Bitcoin reserves have increased the possibility of a "demand shock" - more buyers and fewer tradable tokens. Since the end of 2023, more than 1 million BTC have flowed out of exchanges, mainly due to ETF and institutional hoarding. In addition, the volatility of US Treasury bonds and the weakening of the US dollar are strengthening the safe-haven properties of Bitcoin. In terms of geopolitics, three US states have passed Bitcoin reserve bills, and politicians in Pakistan and the United Kingdom are also considering including BTC in official reserves.
