I. Full Lifecycle Wave Review (2015–2026)

In July 2014, Ethereum completed its ICO at $0.308, raising approximately $18.4 million. The mainnet launched in July 2015, with the first recorded exchange price at $2.92, and in October of the same year it hit an all-time low of $0.42. At this stage, ETH was still a highly experimental blockchain platform with extremely low market awareness.

First Bull-Bear Cycle (2016–2018): Gain 9,383%, Drawdown 94%

After the 2016 DAO incident, the Ethereum ecosystem expanded rapidly. The 2017 ICO frenzy pushed ETH from $7.98 at the start of the year to $881.94, an annual gain of 9,383%, still the highest single-year return of any major asset on record. In January 2018, it peaked at $1,433, then a brutal bear market descended. ETH ultimately crashed from $1,433 to $82.83, a maximum drawdown of 94.2%, taking about 12 months to bottom. This cycle profoundly shaped the market perception of "ETH high volatility, strong cycles."

Second Bull-Bear Cycle (2019–2022): EIP-1559 + NFT Wave

2019 was a bottoming year, with only a slight decline of 2.41% for the full year. The 2020 DeFi Summer ignited ETH demand, combined with the Compound liquidity mining craze. ETH rose from $130 and broke above $4,370 for the first time in May 2021. In September of the same year, the EIP-1559 upgrade went live, introducing a base fee burn mechanism, giving Ethereum a deflationary narrative for the first time. The NFT craze simultaneously boosted momentum, and in November 2021, ETH hit an all-time high of $4,858, with an annual return of 405%. However, the Terra/Luna collapse and the FTX exchange implosion triggered a crisis of confidence in 2022. ETH fell 68.23% for the year, bottoming around $1,008, a drawdown of 79.2% from the ATH, narrowing by about 15 percentage points compared to the first cycle, with increased institutional participation providing some support at the bottom.

Third Bull-Bear Cycle (2023–2026): Institutional Era and L2 Diversion

The 2023 Shanghai upgrade (Shapella) unlocked staking withdrawals, and market fears were quickly dispelled. ETH rebounded from $1,194 to $2,441. In January 2024, the Bitcoin spot ETF was approved, followed by the Ethereum spot ETF in May, with institutions like BlackRock entering. ETH rose to $4,094. In 2025, the L2 ecosystem TVL exceeded $70 billion. Rollup chains like Arbitrum and Base significantly diverted mainnet Ethereum fees. Backed by Pectra upgrade expectations, ETH hit a new high of $4,952 in August 2025. Subsequently, dragged down by the Fed's continued hawkish stance, sustained net outflows from ETF funds, and the L2 "bleeding" effect, ETH entered a 10-month downtrend. In June 2026, it bottomed at $1,508, a drawdown of approximately 69.5% from the ATH, narrowing another 10 percentage points from the second cycle. This bottoming process is not yet clearly concluded.

II. Current Technical Analysis (June 2026)

Over the past 30 days (May 25 – June 25), ETH has completed a full accelerating decline structure. It dropped from $2,113 to $1,621, a 30-day loss of 23.3%.

Key node review: On June 2, it broke below the psychological $2,000 level, triggering the first wave of stop-losses. On June 5–6, it plunged 14.77% over two consecutive days, hitting a low of $1,507.60, followed by strong buying rebound. On June 7, the single-day maximum rebound was 7.70%, confirming real demand near $1,500. On June 15, it briefly pulsed to $1,849 but failed to hold, then slipped back to $1,621 over the next 10 days, showing a classic "crash–rebound–second bottom" structure.

The moving average system is fully bearish. EMA15 is about $1,712, EMA30 about $1,793. Together they form a strong resistance zone, with price firmly suppressed below. The 200-day MA is about $2,351, with a deviation of 31%, indicating extreme trend weakness. RSI(14) is currently around 38.99, weak but not oversold (below 30 is oversold), meaning bears are not yet forced to cover, with room to go lower. MACD formed a death cross near the zero line, momentum continues to release downward, with no bullish divergence signal.

Key price ranges: $1,500–$1,561 is a strong support zone (Bollinger lower band + psychological integer). $1,194 is the 2023 low, i.e., historical structural support. $1,712–$1,793 is the optimal short-entry pressure zone. Above $2,000 enters medium-term resistance.

Core judgment: EMA15 ($1,712) is the watershed for the validity of the bearish trend. As long as ETH daily close does not stand firmly above this level, every bounce is an opportunity to add shorts, not a reversal signal.

III. Historical Bear Market Patterns and Fibonacci Analysis

The consecutive narrowing of drawdowns across three bear cycles is quantitative evidence of ETH maturing: First cycle (2018): from $1,433 to $82.83, max drawdown 94.2%, duration ~12 months. Second cycle (2022): from $4,858 to $1,008, max drawdown 79.2%, duration ~7 months. Third cycle (2025–2026): from $4,952 to known low $1,508, drawdown ~69.5%, duration ~10 months, still ongoing.

Each cycle's drawdown narrowed by about 10–15 percentage points. The structural support behind this comes from: increased institutional holdings (ETFs collectively hold about 11.8 million ETH), staking mechanism locking ~30% of circulating supply, the application-layer moat built by the L2 ecosystem, and exchange balances dropping to three-year lows, shrinking actual selling pressure.

Fibonacci analysis reveals remarkable precision: Stretching Fibonacci from ATH $4,952 to the prior low $1,194, the 0.886 retracement level corresponds exactly to $1,622, while the current ETH price of $1,621 is just $1 off. The 0.886 level is the deepest but most critical defense line in traditional technical analysis; many assets have bottomed and launched major upswings here. The earlier 0.786 level ($1,998) was already broken effectively, and the golden ratio 0.618 ($2,629) was lost as early as the end of 2025.

The ETH/BTC ratio is currently around 0.026–0.027, at the lowest historical range since 2016 (except early 2020), indicating capital is systematically flowing from ETH to BTC. Historical data shows that after the ETH/BTC ratio bottoms in the late bear market, ETH tends to significantly outperform BTC in the subsequent rebound. This ratio is the most critical auxiliary reference for judging whether the market has truly bottomed.

IV. 2026 Bottom Prediction and Rebound Path

Base Case (50% probability): Bottom at $1,400–$1,500. Buying near the current low of $1,508 has been verified by the market. Driven by the Glamsterdam/Pectra upgrade expectations, ETH is expected to complete a second bottom in this range, with a first rebound target of $2,000–$2,200, time window Q3–Q4 2026.

Bearish Case (30% probability): Bottom at $1,200–$1,300. If the Fed unexpectedly maintains high interest rates in H2 or macro risk events hit, ETH could break below $1,500 to $1,200–$1,300. This range corresponds to the cross-validation of Fibonacci 1.0 full retracement and the bear market decay pattern (drawdown of -74% to -76%); a rapid rebound after oversold is highly likely.

Black Swan Case (20% probability): $1,060–$1,194. Extreme scenario under comprehensive macro deterioration (aggressive rate hikes + recession + major L2 security incidents combined), corresponding to the late 2022 bottom area. If actually touched, Ethereum's current fundamentals (institutional adoption, L2 ecosystem, staking infrastructure) are far stronger than in 2022, representing a once-in-a-decade strategic buying opportunity.

Combining the four-dimensional cross-validation (Fibonacci, bear market decay pattern, on-chain cost basis, macro extreme scenario), the probability-weighted ultimate bottom for 2026 is approximately around $1,350, with a range of $1,200–$1,500.

Rebound three-phase path: 2–4 weeks after bottom, short covering pushes ETH to $1,850–$2,000 → Q4 2026 Glamsterdam upgrade catalyzes $2,200–$2,500 → Q1–Q2 2027 rate cut expectations + new narrative drive $2,800–$3,500.

V. Trading Strategy Recommendations (Both Long and Short Perspectives)

Short Strategy (Trend-Following Right Side)

Optimal entry range: $1,712–$1,793 (EMA15–EMA30 dual pressure zone). Operation logic: Wait for ETH to bounce into this range and show clear signs of topping (e.g., long upper wicks, volume contraction), then enter shorts in batches. Do not blindly chase shorts at the current level. Stop loss: above $1,810; once the price effectively stands above EMA30, the bearish logic fails and stop loss should be triggered immediately. First profit target: $1,561 (Bollinger lower band); second target: $1,400–$1,450 (base case bottom area); ultimate target: $1,200–$1,300 (bearish case).

Special note: The biggest hidden cost of shorting is funding rate. When short positions are crowded, funding rates stay negative, eroding profits every 8 hours. For longer-term shorts, it is recommended to hold for no more than 2 months, and before entering, calculate the estimated total cost of 8 weeks of funding rates. Major upgrade news such as Glamsterdam and Pectra, once landing early, could trigger a big green candle breaking all moving averages; this is the biggest risk for short positions, so stop losses must be set and not gambled.

Long Strategy (Left-Side Batch Accumulation)

The current price of $1,621 is already in the first accumulation zone ($1,500–$1,620). Consider entering with 30% of the base position. The second accumulation zone is $1,350–$1,450 (corresponding to the probability-weighted bottom), where an additional 30% can be added. If Scenario C materializes and ETH drops to $1,200–$1,300, deploy the final 40% to full position. Stop loss or reduction criterion: if the weekly close breaks below $1,194, then the previous bottom assumption is invalidated; stop out and re-observe.

Upward take-profit in three stages: $2,000 (short covering + upgrade expectations, first target); $2,500 (Fibonacci 0.618 strong resistance, take profit ~50%); $3,500 (rate cut cycle + new bull narrative, hold remaining until H1 2027). Overall time frame: medium-to-long-term holding for 6–18 months.

Odds reference: Building longs near $1,500, downside risk ~10–25% (to $1,200–$1,350), upside potential ~50–130% (to $2,500–$3,500). This odds structure has occurred only three times in ETH's history: end of 2018, mid-2022, and now. Not investment advice, for reference only.
