Bitcoin (BTC) is speeding up its push toward the $100,000 mark, powered by a surge of capital into spot ETFs and a cluster of supportive technical signals.

The strength on the funding side is the most striking feature of the current market. On Monday, the BTC price briefly climbed to $87,270, a multi-month high, before slipping back below $84,000 as US bond yields rose, though the pullback is seen as a short-lived phenomenon.

Data from SoSoValue shows that, as of Friday, total assets under management across spot Bitcoin ETFs (IBIT.US) had exceeded $134 million, with BlackRock's (BLK.US) IBIT contributing $97 million and Fidelity's FBTC (FBTC.US) adding $49 million, while investors redeemed $11.8 million worth of shares from Bitwise (BITB.US) and other ETFs saw no inflows.

This week, total inflows into spot Bitcoin ETFs reached $2.4 billion, bringing the month-to-date total to $2.7 billion. That marks a third straight month of positive growth for this ETF category, reversing its year-to-date performance and offsetting the $4.5 billion of outflows in June and $2.43 billion in May.

Despite rising US Treasury yields, American investors still expect BTC to rise. Institutional accumulation is proceeding in tandem: Michael Saylor's Strategy (MSTR) bought 95 BTC last week, bringing its total holdings to 846,000 coins, while Strive (ASSR), linked to Vivek Ramaswamy, now holds 26,355 coins.

Futures market indicators compiled by Woofun AI further confirm the strength of demand. Open interest has kept rising this month, with the daily value of open contracts topping $60 billion, pointing to elevated investor risk appetite. At the same time, the "Fear and Greed Index" has remained in greed territory.

From a technical analysis standpoint, a short-term move by BTC to $100,000 is highly likely. On September 11, the 50-day moving average crossed above the 200-day moving average, forming a golden cross. In addition, the chart shows a bullish flag pattern made up of a vertical line and a descending channel. BTC has now broken through the key resistance level of $82,745, which was also the high on May and September 4. Having approached $82,745, BTC is likely to form a "breakout then retest" pattern. As a result, the most probable forecast is that BTC will rebound and reach $100,000, roughly 20% above the current price. Tom Lee believes Bitcoin could climb even higher, forecasting that BTC may rise to $150,000.
