BTCJPY surges by 16.73% over 24 hours as bullish momentum intensifies

On September 12, 2025, BTCJPY surged by 16.73% in a single day, reaching a value of ¥17,063,375. Over the previous week, BTCJPY climbed 330.95%, showed a 685.85% increase in one month, and posted an annual gain of 1581.87%.

In the last 24 hours, the BTCJPY pair has seen a remarkable rally, propelled by ongoing buying momentum and supportive technical signals. Market analysts link this uptick to growing institutional demand for Bitcoin priced in Japanese Yen, as well as broader economic trends that encourage bullish positioning. The upward move was further fueled by a breakout above a significant resistance level that had contained price advances for several weeks.

Technical analysis highlights the strength of this bullish run. The 50-period moving average is trending upward and remains below the current price, pointing to strong buyer momentum. The Relative Strength Index (RSI) has entered overbought levels, which could indicate a brief period of sideways trading. Nevertheless, the robust trading volume and forceful breakout have led many traders to view overbought signals as confirmation of sustained strength rather than an imminent reversal.

The daily candlestick displays a pronounced green body with only small wicks, signaling clear buyer dominance throughout the session. The pair is currently trading near the top of its upward channel, an area analysts are closely watching for either further continuation or a possible pullback. The 200-period moving average is still well beneath the current price, reinforcing the prevailing bullish trend on a larger time frame.

This ongoing surge has piqued the interest of both retail and institutional players, especially those leveraging algorithmic trading to take advantage of the heightened volatility. Over longer periods, BTCJPY is undergoing a rapid revaluation process. The substantial one-month and one-year increases—685.85% and 1581.87%, respectively—suggest a fundamental transformation in how the pair is being valued.

Backtest Hypothesis

A backtesting

has been crafted to assess the potential returns of a systematic BTCJPY trading approach. This method utilizes a mix of moving average crossovers and RSI benchmarks to identify both trend continuation and retracement opportunities. The setup signals a long entry when the price rises above the 50-period moving average and the RSI exceeds 50. A stop loss is set just beneath the 20-period moving average, with a profit target at 1.5 times the entry risk. The strategy is intended for a 90-day historical test, a period during which the pair has shown pronounced directional movement. This corresponds with the technical trends seen in recent sessions and may offer concrete evidence for traders aiming to capitalize on the ongoing bullish momentum.
