Bitcoin (BTC) Holds Above $81,800 Support After Tech-Led Slide

Chip Stocks and Oil Weigh on Bitcoin

Bitcoin (BTC) price spent Monday on the defensive. The coin slid to $81,850 on Binance by 23:09 UTC, 2.15% below its level 24 hours earlier, before settling near $81,980 at the time of writing; on the Korean venue Upbit it printed 111.59 million won at 8:09 a.m. Seoul time on Wednesday, a 1.56% daily drop. The altcoin market fared worse across the same window: Ethereum (ETH) gave up 3.28% to $2,450.72, while XRP shed 4.61% to $1.34, leaving little strength anywhere among large caps. Binance's dollar print and Upbit's won quote moved within a few tenths of a percent of each other, keeping the cross-market gap narrow through the session.

Two forces carried the drop. The first came from US technology shares: the Nasdaq 100 lost 0.7% and a semiconductor-focused index fell 2.7% in the last session, and digital assets, which have traded in step with rate-sensitive equities this quarter, followed the tape lower. The chip weakness traces back to CXMT, the Chinese memory maker, whose announced progress in semiconductor design technology for raising data-storage density rattled the whole group; Micron fell 3.9%, SK Hynix's US-listed ADR dropped 4%, and SanDisk slid 6%. Oil supplied the second force. Brent crude rose 1.8% on Oct. 12, and WTI changed hands at $93.25 per barrel early in Asian hours, down 0.5%, as supply risks around Ukraine's energy network and Houthi attacks directed at Saudi Arabia kept inflation worries priced in. Neither driver is crypto-specific, which is why the selling spread across the sector rather than concentrating around a single story: tokenization firm Securitize extended its losses to 14%. Bitcoin's own dip stayed comparatively shallow at 2.15%, a reminder that the largest asset still absorbs macro shocks with less drawdown than its peers even when the direction is the same.

Leveraged traders absorbed the sharpest losses. Position data covering the past 24 hours shows roughly $106.59 million of Bitcoin (BTC) liquidations, about 86.3% of them long positions betting on continued upside, which works out to nearly $92 million in forced long exits. Across the entire digital-asset market the liquidation tally reached about $485.03 million, with the bulk clustered around the US equity close. Listed crypto mining names fell in sympathy: Bitdeer, Cipher Mining, TeraWulf and HIVE Digital each lost 3-4% of their value, and the exposure is structural, since several of these firms are expanding into AI infrastructure and data-center capacity alongside a core that still rests on proof of work hardware, so a chip-led rout reaches them through both their own earnings and their suppliers' balance sheets. The energy outlook may keep the pressure on. Oxford Economics chief economist Stephen Hare expects Brent to average above $100 per barrel through the second quarter of next year, citing attacks on Red Sea oil export terminals and a prolonged stretch of geopolitical risk. That feeds into the week's decisive print: US CPI data due Wednesday, Oct. 14, the last major reading before the Federal Reserve's October decision. Jason Pride, chief investment strategist at Glenmede, called this CPI the most important indicator to land before the meeting and expects the central bank to stay cautious on further rate hikes unless inflation surprises to the upside. The coin has been hemmed into a narrow band while the macro picture settles: an earlier session note tracked how it steadied near $82,600 after a 2% slide over 24 hours, and Monday's drop moved that band's floor a few hundred dollars lower, while in-house scenario work had already mapped a path to $90,000 before an early $80,000s correction.

Between $81,819 and $84,284

Our composite support and resistance scoring frames the range the market must resolve. The nearest support sits at $81,819, scored 66 out of 100 from the indicators converging there, and the strongest resistance stands at $84,284 with an 88/100 reading, about $2,300 above spot, which last read $81,979 with a 2.07% loss over 24 hours. Momentum screens lean soft, with the RSI at 47.45 and a bearish MACD signal, even as the broader classification remains an uptrend; our Bitcoin technical analysis page tracks both levels live. Positioning has not cracked: perpetual funding holds at 0.0014% and the long/short account ratio stands at 1.61, with 61.7% of accounts long. Which side of the band between $81,819 and $84,284 Wednesday's CPI chooses may decide whether those longs are rewarded or squeezed.
