Bitcoin climbed above $81,000 on Friday, its highest level since September 7. The move came after BTC traded near $76,400 just one day earlier.

BTC reached a high of $81,702 and was trading at around $81,309, up 5.62% on the day.

The surge was driven in part by a short squeeze. Around $192 million in leveraged crypto positions were liquidated within a single hour.

More than $183 million of those were short positions. Bitcoin shorts alone made up about $119 million of the total.

Over a four-hour window, total crypto liquidations across the market hit roughly $300 million.

U.S. spot Bitcoin ETFs added fresh buying pressure, recording about $159 million in inflows on September 17.

Analyst Crypto Patel flagged $83,000 as the level that decides the trend. He wrote: “BTC/USDT is back above $81K, now testing our major $83K resistance. HTF close above $83K → I turn bullish. HTF rejection below $83K → I remain bearish.” Patel added he was letting the higher-timeframe structure confirm direction, without emotion or FOMO.

Rate Hikes and Regulatory Setbacks Failed to Stop the Rally

It was a tough week on the macro side. The Federal Reserve raised its target rate by 25 basis points to 3.75%–4.00% on Wednesday.

The Bank of Japan followed, lifting its policy rate to 1.25%, the highest level in 31 years.

The U.S. dollar index climbed to 100.48 on Friday, a headwind for risk assets.

Bitcoin also absorbed a legislative blow. The U.S. Senate failed to advance the Digital Asset Market Clarity Act, with a cloture vote falling short 49 to 50.

BTC slipped on the news but buyers returned quickly and pushed the price back through key levels.

The CFTC has since submitted a confidential crypto market rulemaking proposal to the White House Office of Information and Regulatory Affairs.

The SEC announced an innovation exemption allowing qualifying platforms up to five years to offer onchain trading in certain tokenized stocks without registering as full securities exchanges.

Traders Eye $83,000–$86,000 as the Next Big Test

Glassnode data shows a cluster of short positions sitting between $83,000 and $86,000, built up over recent weeks.

Straight candle towards $81,000 after flipping $78,000 for support.

What a phenomenal chart it is.

Very likely the markets are proceeding towards $90,000 from here.

Where to buy?

Analyst Michael Van De Poppe has pointed to $78,000 as the first key support level if Bitcoin pulls back. Below that, the $76,400–$76,700 zone is another area of support.

Polymarket traders assign an 84% probability to Bitcoin reaching $84,000 before falling to $55,000.

The platform puts the odds of BTC hitting $90,000 by year-end at 59%. Just 25% of traders expect it to reach $100,000. A 48% probability is assigned to Bitcoin touching $70,000 before the end of the year.
