Bitcoin is hovering just above $85,000, barely batting an eyelash at the softer-than-expected, highly scrutinized U.S. inflation numbers.

Summary
  • Bitcoin remains around $85,000 with little reaction to softer-than-expected U.S. inflation data, as $504M in liquidations hit the market in the past 24 hours.
  • Notable analysts on X are weighing in on Bitcoin’s ongoing price struggles.
  • Traders brace for volatility with the Bank of Japan’s upcoming decision and Bitcoin facing key resistance at $88K while support holds near $85.4K.

Trader insights

Crypto chart guru Ali Martinez notes that Bitcoin is still stuck in a box on lower timeframes, facing resistance just under $90,000 and finding support near $85,400. A breakout could kick-start some bullish vibes, while a breakdown could mean more pain ahead.

Daan Crypto Trades also provided an interesting take.

Bitcoin is likely to see a larger price move before the end of the month, citing historical patterns in monthly trading ranges.

So far, Bitcoin’s distance between its monthly low and high is about 12%, which is smaller than usual, as monthly candles typically show wider price swings more than 90% of the time. It is statistically unlikely, therefore, that both the monthly high and low were set early in the month.

This suggests one of those levels is still likely to be breached. While the data does not indicate direction, it implies heightened volatility ahead, with Bitcoin positioned near the middle of its monthly range and at least a 5% move needed to test either extreme.

The analyst pointed to the Bank of Japan’s policy decision as the most critical catalyst of the week, noting that while equities such as the Nasdaq are rallying and gold remains stable, cryptocurrencies are lagging as traders brace for the possibility of a rate hike.

An update on the $BTC chart.

Great CPI news, some upwards momentum, and then, again, a harsh correction.

It's clear that the $88K level is the ultimate one, and that's what the markets need to break up in order to be getting some momentum.

It's also quite clear that the BoJ… pic.twitter.com/vYpA2MwYLe
