The leading cryptocurrency by market capitalization momentarily pierced the $82,000 mark during the previous trading session, reaching heights not witnessed since late April.Bitcoin (BTC) PriceThe upward price action stems primarily from diminishing anxieties surrounding potential Federal Reserve interest rate increases. Federal Reserve Governor Christopher Waller informed Reuters that he’s inclined to maintain current interest rate levels at the central bank’s next policy meeting, especially should upcoming inflation figures demonstrate moderation.Waller’s statements catalyzed a notable decline in US Treasury yields. This development carries significant implications for Bitcoin, as the cryptocurrency exhibits sensitivity to yield fluctuations due to its risk-on characteristics. After Waller’s public comments, the likelihood of a September rate increase tracked by CME Fedwatch declined to 50.4%, down from above 60% earlier during the week.Market analyst Ash Crypto shared on X that Bitcoin successfully breached the Weekly 50-day moving average positioned at $80,400, characterizing it as a “massive breakout.” The analyst pinpointed $83,000 as the subsequent significant resistance barrier, suggesting that a weekly close above the 50 MA would validate the commencement of a fresh bull market cycle.MASSIVE BREAKOUT IN BITCOIN$BTC is trading above the Weekly MA 50 at $80,400, with $83K now the next major resistance.If BTC closes weekly candle above 50 MA and holds that level it will confirm the bull market has started. pic.twitter.com/2rI2qZx7up— Ash Crypto (@AshCrypto) September 3, 2026Bitcoin ETF Demand Reaches Eight-Month PeakUnited States-based spot Bitcoin exchange-traded funds registered $730.9 million in net inflows on Thursday, representing the strongest daily performance since January 14, when these investment vehicles captured $843.6 million.
