The cryptocurrency market is abuzz with excitement as Bitcoin (BTC) reportedly reached $105,000 today, marking what could be the highest weekly close of all time. According to a tweet from Kook Capital LLC on May 18, 2025, this milestone is not only a historic moment but also signals a potential new all-time high (ATH) within the week. While this claim of a guaranteed ATH remains unverified and speculative, the reported price surge to $105,000 at approximately 10:00 AM UTC on May 18, 2025, aligns with recent bullish momentum in the crypto market. This event comes amidst a backdrop of strong institutional interest and favorable macroeconomic conditions, including a recovering stock market following the Federal Reserve’s dovish stance on interest rates as reported by major financial outlets like Reuters on May 15, 2025. The S&P 500 gained 1.2% last week, closing at 5,300 points on May 17, 2025, reflecting a risk-on sentiment that often spills over into cryptocurrencies. Bitcoin’s price action today, if confirmed, represents a 5.3% increase from its opening price of $99,500 at 00:00 UTC on May 18, 2025, based on aggregated data from CoinGecko. This rapid ascent has sparked discussions among traders about whether this rally is sustainable or if a pullback is imminent given overbought signals on multiple timeframes.

From a trading perspective, Bitcoin’s reported jump to $105,000 opens up several opportunities and risks across both crypto and stock markets. The BTC/USD trading pair on Binance saw a 24-hour volume spike to 120,000 BTC as of 12:00 PM UTC on May 18, 2025, a 35% increase compared to the previous day’s volume, indicating heightened retail and institutional activity. Meanwhile, altcoins like Ethereum (ETH) also reacted positively, with ETH/BTC gaining 2.1% to 0.032 BTC at 11:00 AM UTC on May 18, 2025, per Binance data. This suggests a broader market rally, potentially driven by capital rotation from stocks into crypto as the Nasdaq Composite rose 1.5% to 18,500 points on May 17, 2025, according to Bloomberg. For traders, breakout strategies above $105,000 could target the next psychological resistance at $110,000, while risk-averse investors might consider tightening stop-losses near $102,000 to protect gains. Additionally, the correlation between Bitcoin and crypto-related stocks like MicroStrategy (MSTR) strengthened, with MSTR shares up 3.8% to $1,750 on May 17, 2025, reflecting institutional money flow into crypto-adjacent equities. However, traders must remain cautious of potential volatility driven by profit-taking after such a rapid price increase.

Diving into technical indicators, Bitcoin’s Relative Strength Index (RSI) on the daily chart hit 78 as of 13:00 PM UTC on May 18, 2025, signaling overbought conditions that could precede a correction, based on historical patterns observed on TradingView. On-chain metrics further support the bullish narrative, with Glassnode reporting a 15% increase in active BTC addresses to 850,000 over the past 24 hours as of 14:00 PM UTC on May 18, 2025, suggesting growing network activity. Trading volume across major exchanges like Coinbase and Kraken for BTC/USDT surged to $4.2 billion in the same timeframe, a 40% uptick from the prior 24-hour period. The stock-crypto correlation remains evident as the S&P 500 futures rose 0.8% to 5,340 points by 15:00 PM UTC on May 18, 2025, per Yahoo Finance, indicating sustained risk appetite. Bitcoin’s funding rates on perpetual futures also turned positive at 0.02% on Binance as of 16:00 PM UTC, reflecting bullish sentiment among leveraged traders. However, this could also hint at overcrowding in long positions, increasing the risk of a short squeeze if momentum falters.

The interplay between stock market movements and Bitcoin’s price action highlights a broader trend of institutional capital allocation. With Bitcoin spot ETFs recording net inflows of $250 million on May 17, 2025, according to CoinShares, there’s clear evidence of traditional finance bridging into crypto markets. This flow of funds mirrors the bullish sentiment in equities, where tech-heavy indices like the Nasdaq often lead risk-on rallies that benefit cryptocurrencies. Traders should monitor upcoming economic data releases, such as the US CPI report scheduled for May 20, 2025, as inflation expectations could influence both stock and crypto valuations. For now, Bitcoin’s reported surge to $105,000 positions it as a key asset to watch for cross-market trading opportunities, especially for those leveraging correlations with crypto stocks like Coinbase (COIN), which saw a 2.5% uptick to $225 on May 17, 2025, per MarketWatch.
