This was a big milestone, which has come to be referred to as the Bitcoin new ATH, a great beginning to the "Uptober" rally, a time that tends to be bullish for crypto.

Investors are now eager to know if this pace will trigger another record-breaking streak as the year picks up its last quarter.

Institutional ETF Inflows Power Bitcoin's Surge

One major reason for this Bitcoin new ATH is the increasing presence of institutional investors. U.S. spot Bitcoin ETFs saw a net inflow of $3.24 billion last week alone, reflecting increased confidence among large funds and financial institutions.

BlackRock's IBIT already holds more than 890,000 BTC, and institutions such as Standard Chartered and Citigroup have increased their year-end targets to $135K and $133K respectively.

These inflows take away from the supply of BTC in the market, leaving it scarcer and increasingly driving prices higher.

Entities like Metaplanet and MicroStrategy are stocking up on additional BTC in their treasuries as well.

Reserves at exchanges have fallen to a seven-year low, translating to fewer coins sold, another bullish indicator behind the new all time high.

Technical Indicators Signal Strong Momentum

Bitcoin price charts reflect ongoing strength.

The MACD is still bullish, and the RSI of 69 indicates strong momentum without being overbought.

Now that the previous high of $123,944 has been broken, analysts now eye $128,000 as the next significant level.

If it closes above $126K, another leg higher could ensue, driving the Bitcoin new ATH even higher.

Open interest in the futures market remains elevated, indicating the presence of bulls as well as bears. There is a possibility of a short-term pullback with support to be seen between $113K and $120K.

However, the overall sentiment remains optimistic as long as the buying pressure remains robust.

Macro Factors and Global Market Influence

Global economic developments are also determining Bitcoin's trajectory. The U.S. Federal Reserve is due to reduce interest rates by 0.25%, a step which tends to lift risk assets such as crypto.

Meanwhile, worries regarding the potential U.S. government shutdown are compelling more investors to consider crypto as an alternative value store.

Whale activity has picked up, with approximately 12,000 BTC transferred to exchanges last week adding some near-term volatility.

Despite that, long-term investors currently control approximately 68% of Bitcoin's total supply, which is good news for market stability and for sustaining this Bitcoin new ATH.

The spot-to-perpetual trading ratio is 0.41, still indicating healthy demand from actual buyers, not simply leveraged speculators.

Uptober Momentum: Carrying Over Into Moonvember and Bullcember

October has often been kind to the cryptocurrency, and this year is proving no different. If ETF inflows and buying pressure continue, Bitcoin price prediction says it could soon test $130K.

Traders believe the current BTC new all time high could extend into November and December, months called “Moonvember” and “Bullcember”, when crypto markets often see strong rallies and excitement.

Conclusion

Bitcoin's surge over $125,000 is another significant milestone in its history.

This Bitcoin new ATH indicates how much the market has evolved, powered by institutional flows, technical support, and the consistent Uptober trend.

Short-term volatility can never be ruled out, but the longer-term outlook is encouraging.

If such trends persist, it may be on the cusp of another strong bull run as we approach 2026.
