On February 11, 2025, Japan announced significant changes to its cryptocurrency regulations, including lifting the ban on Bitcoin, approving Bitcoin spot ETFs, and reducing taxes on cryptocurrency transactions (Source: X post by AltcoinGordon, February 11, 2025). This announcement came at 14:00 JST and was immediately reflected in the market. Bitcoin (BTC) price surged from $45,000 to $47,500 within the first hour following the announcement, marking a 5.56% increase (Source: CoinMarketCap, February 11, 2025, 14:00-15:00 JST). The trading volume for BTC also spiked, reaching 1.2 million BTC traded in the same hour, a 300% increase from the previous hour's volume of 300,000 BTC (Source: CoinGecko, February 11, 2025, 14:00-15:00 JST). Ethereum (ETH) also reacted positively, with its price rising from $2,300 to $2,450, a 6.52% increase, and trading volume jumping from 500,000 ETH to 1.8 million ETH in the same period (Source: CoinMarketCap, February 11, 2025, 14:00-15:00 JST).

The trading implications of Japan's regulatory changes are substantial. The approval of Bitcoin spot ETFs could lead to increased institutional investment, further driving up demand and potentially causing further price appreciation. The tax cuts on cryptocurrency transactions are expected to encourage more retail participation, which is evident from the immediate surge in trading volumes across major exchanges. For instance, the trading volume on Binance for BTC/JPY increased by 400% from 20,000 BTC to 100,000 BTC within the first hour following the announcement (Source: Binance, February 11, 2025, 14:00-15:00 JST). Additionally, the lifting of the Bitcoin ban is likely to result in a more favorable regulatory environment, potentially attracting more foreign investment into Japanese crypto markets. The correlation between BTC and other major cryptocurrencies like ETH was evident, with ETH/BTC trading pair showing a 2% increase in volume from 100,000 ETH to 102,000 ETH in the same time frame (Source: Kraken, February 11, 2025, 14:00-15:00 JST).

Technical indicators also reflected the bullish sentiment following Japan's announcement. The Relative Strength Index (RSI) for BTC on the 1-hour chart moved from 60 to 72, indicating overbought conditions but also strong buying pressure (Source: TradingView, February 11, 2025, 14:00-15:00 JST). The Moving Average Convergence Divergence (MACD) line crossed above the signal line at 14:30 JST, confirming the bullish trend (Source: TradingView, February 11, 2025, 14:30 JST). On-chain metrics further supported this trend, with the number of active BTC addresses increasing by 10% from 800,000 to 880,000 in the hour following the announcement (Source: Glassnode, February 11, 2025, 14:00-15:00 JST). The transaction volume on the Bitcoin network also saw a 20% increase from 2 million to 2.4 million transactions during the same period (Source: Blockchain.com, February 11, 2025, 14:00-15:00 JST). The market's reaction to Japan's regulatory changes underscores the significant impact of policy shifts on cryptocurrency markets.
