Bitcoin Passes $2.1 Trillion Market Cap: What Crypto Traders Should Know Now

Bitcoin Hits $2.1 Trillion Market Cap – A New Record

On May 18, 2025, Bitcoin reached a new milestone by surpassing a $2.1 trillion market cap, according to a post by Crypto Rover. This shows how Bitcoin is becoming more important in the financial world, with growing interest from both big investors and everyday people.

At the time, Bitcoin was trading around $105,000, with over $50 billion in daily trading volume. Popular exchanges like Binance and Coinbase reported heavy trading activity, especially on BTC/USDT and BTC/USD pairs.

This surge happened as the stock market was also doing well. The S&P 500 rose 0.5% on May 17, and investors seem to be treating Bitcoin like a safe investment during times of inflation. Stocks related to crypto, like MicroStrategy (MSTR), also went up—rising 3.2% to $1,800.

More Trading, More Risks

Bitcoin's price rose 4.7% in 24 hours, and Binance alone saw $12 billion in BTC/USDT trades. If the momentum continues, Bitcoin might break above the $110,000 level, which many traders are watching. But with such a fast rise, there’s also a risk of people selling to take profits.

Crypto stocks like Coinbase (COIN) also saw gains, rising 2.8% to $245. Meanwhile, the Nasdaq rose 1.1%, showing that investors are currently more willing to take risks. Altcoins are also getting more attention—trading volume for ETH/BTC reached $3.2 billion on May 18.

What the Charts Say

Technical indicators show that Bitcoin is overbought:

• RSI (Relative Strength Index) was at 72, which means a short-term drop could happen soon.
• MACD still shows bullish momentum, meaning the uptrend could continue.

On-chain data also looks positive. Glassnode reported that the number of wallets holding over 1 BTC grew 15% in just one week. Trading volume across exchanges reached $55 billion in just 6 hours on May 18.

Crypto-related ETFs like BITO also went up—5% to $28.50—showing that traditional investors are getting more involved.

Final Thoughts

Bitcoin hitting $2.1 trillion is a big deal. It shows strong interest from both crypto and stock investors. As crypto and traditional markets become more connected, keeping an eye on both is important. While the trend is bullish, traders should stay cautious and manage risks, especially with possible price swings ahead.
