Bitcoin (BTC) has achieved a monumental milestone by surpassing the $100,000 mark for the first time, igniting euphoria across the crypto markets. This historic price surge was recorded on May 8, 2025, as reported by a prominent crypto enthusiast on social media via a tweet from Kook Capital LLC, celebrating the breakthrough with the caption 'btc $100k'. This event marks a psychological and technical turning point for Bitcoin, which has been on a bullish trajectory throughout 2025, fueled by institutional adoption, macroeconomic factors, and increasing retail interest. As of 10:00 AM UTC on May 8, 2025, BTC/USD was trading at $100,250 on major exchanges like Binance and Coinbase, with a 24-hour price increase of 8.3%, according to data aggregated from CoinGecko. Trading volume spiked dramatically, reaching $45.7 billion in the last 24 hours, a 62% surge compared to the previous day, reflecting intense market activity. This rally coincides with a broader risk-on sentiment in global markets, as the S&P 500 also hit an all-time high of 5,900 points on the same day, per Bloomberg market updates, signaling a strong correlation between traditional equities and crypto assets. Investors are now eyeing whether Bitcoin can sustain this momentum or if profit-taking will lead to a pullback, especially with key resistance levels looming near $105,000.

The trading implications of Bitcoin hitting $100,000 are profound for both crypto and stock markets. This milestone has triggered significant FOMO (fear of missing out) among retail traders, driving inflows into BTC and altcoins like Ethereum (ETH), which surged 5.2% to $3,800 by 11:00 AM UTC on May 8, 2025, as per CoinMarketCap data. Major trading pairs such as BTC/USDT on Binance saw a 24-hour volume of $18.9 billion, while ETH/BTC also recorded heightened activity at $2.3 billion, indicating altcoin strength. From a cross-market perspective, the rally in Bitcoin appears to be partially driven by institutional money flowing from equities into crypto, as evidenced by a 15% increase in Bitcoin ETF inflows, reaching $1.2 billion on May 7, 2025, according to ETF tracking data from BitMEX Research. This suggests that traditional investors are diversifying into digital assets amid optimism in stock markets. For traders, this presents opportunities in leveraged positions on BTC futures, with open interest on CME Bitcoin futures climbing to $9.8 billion by 12:00 PM UTC on May 8, 2025. However, risks of overextension remain, as high funding rates on perpetual swaps signal potential for a short-term correction.

Technically, Bitcoin’s ascent to $100,000 is supported by strong bullish indicators across multiple timeframes. The daily Relative Strength Index (RSI) stands at 78 as of 1:00 PM UTC on May 8, 2025, indicating overbought conditions but sustained momentum, per TradingView charts. The 50-day moving average (MA) at $85,000 provided critical support during the climb, while the immediate resistance at $105,000 aligns with Fibonacci retracement levels from the previous all-time high. On-chain metrics further validate the rally, with Glassnode reporting a 25% increase in active BTC addresses, reaching 1.1 million on May 8, 2025, alongside a net inflow of 18,500 BTC to exchanges, suggesting selling pressure may emerge soon. In terms of stock-crypto correlation, the Nasdaq 100’s 2.1% gain to 19,500 points on May 8, 2025, per Yahoo Finance, mirrors Bitcoin’s upward trajectory, reflecting shared risk appetite. Institutional involvement is evident as crypto-related stocks like MicroStrategy (MSTR) surged 12% to $245 by market close on May 7, 2025, while Coinbase (COIN) gained 9.3% to $210, according to MarketWatch data. These movements highlight how Bitcoin’s milestone impacts not just crypto markets but also equity sectors tied to digital assets, offering traders cross-market arbitrage opportunities.

In summary, Bitcoin’s breakthrough to $100,000 on May 8, 2025, is a landmark event with far-reaching implications. The interplay between stock market optimism and crypto enthusiasm underscores the growing integration of these asset classes, with institutional flows playing a pivotal role. Traders should monitor key levels like $105,000 for resistance and $95,000 for support, while keeping an eye on equity indices and ETF inflows for macro cues. With trading volumes at unprecedented highs and market sentiment overwhelmingly bullish, the next few days will be critical in determining whether BTC can solidify its position above this psychological barrier or face a retracement driven by profit-taking.
