[DigitalToday reporter Hyunwoo Choo] Bitcoin rose as it tried to regain support around $80,000, climbing as high as $81,687 intraday. Cointelegraph reported on Tuesday that bitcoin moved back toward $82,000 as Asian markets and U.S. technology stocks rebounded.

The bitcoin-dollar pair hit $81,687 intraday on Bitstamp, according to TradingView. The hourly chart did not make a new low, and buying liquidity around $79,000 and $80,000 also thickened, according to Coinglass data.

Crypto markets gradually turned stronger as concerns eased over AI investment spending and debt financing. South Korea's KOSPI index rose 6.6 percent on Tuesday, returning above the 6,000 level for the first time since Oct. 14. Its weekly gain was 9.3 percent.

In the United States, the tech-heavy Nasdaq Composite Index closed up 1.1 percent on Monday. The move came ahead of earnings reports from Microsoft, Alphabet, Amazon and Intel. Samsung Electronics is scheduled to report third-quarter earnings on Wednesday.

Mike Wilson, Morgan Stanley's chief U.S. equity strategist, said in a CNBC interview that tech stocks were entering a new bull phase after a sell-off in early October. He said most of the correction was already over and the market had absorbed it very efficiently.

Markets priced in a 90.6 percent chance that the Federal Reserve will keep its policy rate unchanged at 3.75 to 4 percent at its meeting on Tuesday. That was based on CME Group's FedWatch.

It is still unclear whether bitcoin has created a new price range on a weekly basis. Crypto trader Rekt Capital said the current weekly chart resembled the structure of the 2022 bear market. He said it was still unclear whether bitcoin could form a new price range above resistance near $82,000.

Rekt Capital said bitcoin had not yet broken out of the macro accumulation range pattern between $60,000 and $80,000 on a weekly basis.
