Bitcoin (BTC) was trading a hair's breadth away from its all-time high on Tuesday, as analysts plotted one final move higher in the coming days.

Futures open interest across major exchanges hit $75 billion, an all-time high in U.S. dollar terms, as traders upped their leveraged positioning. That came alongside a continued rally in spot markets, with BTC holding above $100,000 for more than 11 straight days - a sign, some traders said, of accumulation and strength at current levels.

"The current price action appears to be a consolidation phase," said Ruslan Lienkha, chief of markets at YouHodler, in an email. "It's marked by accumulation, potentially setting the stage for another leg higher that could lead to a new all-time high."

Bitcoin was last changing hands above $107,500, up nearly 1.5% over the past 24 hours. Ether (ETH) and Solana's SOL added 2%, while dogecoin (DOGE), Cardano's ADA and xrp (XRP) bumped 3%.

Derivatives data supported the bullish outlook. The call-to-put open interest ratio reached 1.55 this weekend. At the same time, premiums for out-of-the-money calls rose across the board, a sign traders are positioning for a breakout, HTX Research's Chloe Zheng said in a weekend update shared with CoinDesk.

At the same time, short-term implied volatility (IV) dropped to an 18-month low of 35–40%, reflecting a relatively calm backdrop despite rising positioning, HTX said.

"This mix of euphoric sentiment and low volatility often conceals the build-up of excessive leverage," HTX Research noted. "But under such conditions, Bitcoin could retest new highs within 30–45 days."

Still, resistance at the $107,000 level has held for now. FxPro analyst Alex Kuptsikevich said in an email that the market is driven by "a crowd of retail investors" and momentum-chasing traders who remain undeterred by macro uncertainty or recent exchange security concerns.

"Further dynamics will depend on changes in global risk appetite," Kuptsikevich wrote. "If the resistance at $107K is broken, there are more chances to restore the uptrend. That opens a path toward $115K."
