Miner capitulation for 287 days + $15 billion in stablecoin evaporation: How much longer will BTC’s "dual dehydration" continue?
If you’ve only been looking at on-chain data for price lately, you may have missed two structural changes unfolding in parallel—one is the ongoing miner capitulation, and the other is the epic contraction of stablecoins. Looking at either signal alone is worth paying attention to, but together they may describe the most important on-chain narrative of the 2026 crypto market.

## Signal 1: Miner capitulation has lasted 287 days, with a 19.9% difficulty pullback
According to the latest analysis from Bitcoin Magazine Pro, the total hashrate across the Bitcoin network has been in a decline for approximately 287 consecutive days. This is one of the longest-lasting hashrate contraction cycles since the widespread adoption of ASIC mining rigs.
In sync with this, mining difficulty has fallen 19.9% from its historical peak. What does that mean? A drop in difficulty means fewer machines are participating in mining—miners are shutting down. In the ASIC era, the only times the difficulty pullback exceeded this figure were just two: one in 2021 when China banned mining (policy forced shutdown), and the other at the 2018 bear-market bottom.
But this time is different. This time there isn’t a single external shock event; instead it’s a slow, economically driven "chronic bleeding."
**Puell Multiple tells you how painful things are for miners.** Puell Multiple is a classic metric for measuring miner income pressure (calculation: daily miner revenue ÷ the average daily revenue over the past 365 days). The current value is about 0.75, meaning miners’ current daily income is only 75% of the average level over the past year. In dollar terms, daily revenue is about $30 million, while the long-term mean is close to $40 million.
What’s even more striking is the fee data. Current daily fee income for miners is only about $200,000, and the total fee income over 28 days isn’t even enough to cover the block reward of a single block (about 3.125 BTC, worth roughly $200,000). The Bitcoin network produces about 144 blocks per day, meaning fees can only support the network’s security budget for about 10 minutes.
This isn’t alarmism—it’s an objective reflection of on-chain data.

## Miners are selling coins, but miner stocks are surging
Here’s a very counterintuitive phenomenon: over the past year, BTC is down about 46%, yet the stock prices of listed mining companies have broadly surged—Hut 8 is up 431%, Riot Platforms is up 62%, and HIVE Digital is up 37%.
Why? Because miners are no longer just miners.
Core Scientific signed an AI data center cooperation agreement with AMD of up to 2.5GW. Hut 8 has signed multi-billion-dollar long-term compute service contracts. Bitdeer’s AI cloud business has annualized revenue of $76 million, with 95% GPU utilization.
Investors no longer value mining companies as "leveraged BTC." Instead, they treat them as AI infrastructure providers. This explains why miners are selling coins to survive (selling more than 32,000 BTC in the first quarter), yet stocks are skyrocketing—the market’s pricing logic has changed.
**What does this mean for BTC?** Miners’ computing power is shifting from securing the BTC network to AI computing. In the short term this won’t create a security risk (hashrate is still high enough), but in the long run, if block subsidies continue to be halved while fee income doesn’t grow, the security budget shortfall will widen.

## Signal two: stablecoins “evaporate” $15 billion, the biggest contraction since 2022
If you think the miner story is already heavy enough, take a look at stablecoins next.
According to DeFiLlama data, stablecoin total supply has fallen from a peak of $322.1B in mid-May to about $307.6B as of August 2—an evaporation of roughly $14.5B. This is the largest stablecoin contraction since the 2022 Terra crash.
Of that,
- USDT fell from $189.0B in May to $183.2B, down about $5.8B
- USDC fell from a March peak of $80B to $72.1B, down about $7.9B
- In June alone, net outflows of $11.4B— the worst month since the Terra event
Over the past 7 days, $2.77 billion has flowed out again. By August 5, the total market cap had fallen further to about $298.3 billion.
**Why are stablecoins shrinking?** Three reasons:
First, the GENIUS Act. The (GENIUS Act), effective in July 2025, bans licensed stablecoin issuers from paying interest to holders. This means that funds previously used to treat USDT/USDC as "yielding dollars" no longer have a reason to keep being held. Those funds have flowed into tokenized Treasury products—whose size is now close to $17 billion. More broadly, RWA (real-world assets on-chain) holdings exceed $32 billion.
Second, trading demand is declining. In Q2 2026, crypto prices fell, trading volumes shrank, and naturally the demand for stablecoins as trading collateral decreased.
Third, Europe’s MiCA regulations limit the market. Some non-compliant stablecoins were removed from European exchanges, further compressing supply.

## "Dual dehydration": a vicious cycle of liquidity drain + miner sell pressure
When you put the two signals together, you’ll notice an unsettling compounding effect:
**Miners are selling coins** (because income has dropped and they need to sell BTC to cover operating costs) → BTC price faces pressure → trading activity declines → stablecoin demand decreases → stablecoin supply contracts → available market liquidity falls → price faces further pressure → miner income drops further → continued selling.
This is what I mean by "dual dehydration"—liquidity dehydration happens simultaneously on the miner side (revenue drying up) and on the market side (liquidity draining), and they amplify each other in a positive feedback loop.
But there’s also good news: the actual usage of stablecoin networks is breaking records. According to Visa’s on-chain analytics dashboard data, in June the stablecoin-adjusted trading volume reached about $1.8 trillion, up 63% month-over-month. USDC handled about $1.21 trillion, and USDT handled about $576 billion.
So what does this mean? Stablecoins are shifting from "speculative collateral" to "payment tools." Even as supply decreases, the turnover rate of each stablecoin is increasing. This is a structurally positive change—though in the short term a supply squeeze puts pressure on prices, in the long run the strengthening of payment utility may be more valuable than simply having more supply.

## Trading volume divergence: USDC processes more transactions with a smaller supply
Here’s a detail worth digging into. The USDT supply is 2.5 times that of USDC ($183.2B vs $72.1B), but USDC’s monthly trading volume is actually double USDT’s ($1.21T vs $576B).
This means USDC’s average turnover speed is about 5x that of USDT. The reason may relate to user composition—USDC is used more by institutions and enterprises for settlement and payments, leading to higher turnover frequency; USDT is used more by retail users for trading positions, resulting in slower circulation.
If you’re a trader, this data is a reminder: don’t judge market liquidity only by the total stablecoin amount. You also need to look at turnover. Total supply is shrinking, but turnover is accelerating—so the actual "effective liquidity" may be more optimistic than the book numbers suggest.

## Historical analogies from on-chain data: Will this time be different?
The miner stress composite indicator (combining Puell Multiple and a reverse miner capitulation index) has fallen to a new low in 2026, deep within the "undervalued" range. Historically, similar synchronized collapses occurred near major bottoms in 2015, 2018, 2020, 2022, and 2024.
In 2015, within less than a week after the indicator touched 0.00, BTC crashed from about $300 to $160, then began a new cycle.
Will this repeat this time? No one knows. But on-chain data tells us: current miner stress is at a historically rare extreme level, and the contraction speed of stablecoin liquidity is the fastest since Terra.
These two signals are either "darkness before dawn"—extreme pessimism often marks the cycle bottom—or the "start of a new normal"—miners structurally shifting toward AI, stablecoins structurally shifting toward payments. The old valuation framework may no longer apply.

## Three on-chain observation indicators for traders
If you want to track these signals yourself over the coming weeks, focus on these three data points:
**1. Has the Puell Multiple fallen below 0.5?** Current value is 0.75. If it further drops to below 0.5, it means miner income pressure has entered an extreme zone—historically, this is typically a cycle-bottom signal.
**2. Is the total stablecoin supply stabilizing?** Current is $298.3B. If it stops falling for two consecutive weeks, it suggests that liquidity outflows have hit a floor, which may indicate the market is forming a base.
**3. Changes in miners’ BTC holdings.** Watch CryptoQuant’s Miner Reserve indicator—if miners stop net outflows, it means selling pressure has weakened, which is one of the bottom-confirmation signals.
On-chain data won’t tell you whether prices will go up or down tomorrow, but it can tell you where we currently are in the cycle. And right now, calling this an "extreme range" isn’t an overstatement.
