Bitcoin’s 2025 August Surge: 3 Bullish Signals That Prove This Rally Has Legs

Bitcoin isn't just holding gains—it's gearing up for the next leg up. Three key metrics suggest the king of crypto isn't done yet.

1. Institutional inflows break records

Wall Street's latest filings show billion-dollar positions being opened—hedge funds aren't just dipping toes anymore.

2. Miner capitulation? Not this time

Hash rate stability defies the usual post-halving slump. These diamond-handed miners know something retail doesn't.

3. Options market screams 'FOMO'

Call option volumes hit year-to-date highs as traders bet big on Q3 fireworks. (Because clearly, nobody learned from 2021.)

The charts say bull market. The fundamentals say bull market. And if history repeats? Well—let's just hope your bags are packed.

1. Bitcoin Futures-to-Spot Ratio

The first is the Futures-to-Spot Ratio, which has dropped to its lowest level since October 2022. Why is this significant?

According to Swissblock, this ratio measures futures trading volume compared to spot trading volume. A lower ratio indicates that large investors — often called massive allocators — are actively buying BTC on the spot market instead of speculating via futures.

“Since the April low, this MOVE has been spot-driven — massive allocators hoovering up every last BTC. Futures-to-spot ratio is back to Oct 2022 lows → a signal of epic spot demand,” Swissblock reported.

Historically, when this ratio plunges, it often marks the cycle’s bottom — similar to late 2022 before BTC skyrocketed above $100,000. This suggests that even with bitcoin already in six-figure territory, the rally might still be in its early stages.

“The $120.5K breakout target has been hit, now what? Price momentum is aligning… Yes, macro volatility is expected and downside pressure may Flare up, but with momentum igniting, we go higher,” Swissblock predicted.

2. CEX Volume Ratio: Bitcoin vs. Altcoins

The second metric is the spot trading volume ratio between Bitcoin and altcoins.

This ratio compares BTC’s spot trading volume to altcoins on centralized exchanges (CEX). When the ratio rises, it shows Bitcoin is attracting more capital — a classic sign of “Bitcoin Season.”

CryptoQuant data reveals that this ratio tends to rise alongside Bitcoin’s price. In August 2025, it has rebounded to 3 — its highest since July 2022. This means Bitcoin’s trading volume is now triple that of all altcoins combined.

History shows that when the ratio surpasses 3 and moves toward 5 (as it did in late 2021), BTC often leads strong market rallies. This suggests that today’s market conditions indicate Bitcoin Season hasn’t yet reached its full potential.

3. Bitcoin Taker Buy-Sell Ratio

Finally, the Taker Buy-Sell Ratio indicates that new buying momentum is building strongly.

According to CryptoQuant analyst Crazzyblockk, this ratio measures the buying volume divided by the selling volume from takers — the active traders initiating market orders.

“Takers set the immediate tone of the market — when they’re aggressively buying, it often precedes bullish moves; when selling dominates, it can signal downside risk,” Crazzyblockk explained.

A value above 1 signals bullish sentiment. Crazzyblockk also notes that when this value exceeds its 7-day average, it signals fresh buying momentum.

This signal was confirmed in August. The Bitcoin Taker Buy-Sell Ratio exceeded its 7-day average and reached 1.21 — the highest since March.

These three metrics — record-low Futures-to-Spot Ratio, recovering CEX Volume Ratio, and bullish Taker Buy-Sell Ratio — all point to Bitcoin Season kicking off in August 2025.

Additionally, recent BeInCrypto analysis suggests Bitcoin could climb further. However, it warns that a drop below $118,900 WOULD invalidate the short-term bullish trend.
