Bitcoin and Ethereum are both well below their all-time highs, ETF flows are shifting, and two major September events could reshape the market entirely. Which coin has a realistic shot at recovery by 2028, and which faces a steeper climb…

Bitcoin (CRYPTO: BTC) trades near $77,100 today, and Ethereum (CRYPTO: ETH) trades near $2,457. Both have slipped over the past week, but their distance from their previous records shows how much ground each would need to recover. Bitcoin needs a 63.4% gain to return to $126,000, while Ethereum needs a 101.5% gain to reach $4,953.
Both coins are down in 2026, although Ethereum has outpaced Bitcoin over the past 30 days. Bitcoin’s ETF market has recently shown strong demand, with several weeks of sizable inflows before investors pulled money out again in the latest session. The bigger question is whether those differences will still matter two years from now and where each cryptocurrency could trade by September 2028.
Bitcoin Needs a 62% Gain to Reach Its ATH While Ethereum Needs 98%
From about $77,100, Bitcoin needs a 63.4% gain to reclaim its $126,000 all-time high, set in October 2025. Reaching that level would take Bitcoin to roughly 1.63 times its current price, giving it a substantial recovery ahead but a much shorter climb than Ethereum faces.
Ethereum faces a much bigger recovery to its all-time high is $4,953. From about $2,457, ETH needs a 101.5% gain to return to that level, meaning it would need to more than double from its current price just to get back to its previous record.
The gap is also visible when compared with where both cryptocurrencies started 2026. Bitcoin opened the year around $87,500 and is now about 11.9% below that level. It needs roughly a 13.5% gain to get back to its January price. Ethereum began trading in 2026 around $2,967 and is about 17.2% lower today. It needs a 20.7% gain to recover its January level. Bitcoin therefore has the shorter climb both to its 2026 starting point and to its all-time high.
However, in the near term, Ethereum has had the better run. Bitcoin is down 4.79% over the past week, while Ethereum has slipped just 1.50%. Over the past month, the gap is even wider, with Bitcoin up 21.77% compared with Ethereum’s 31.37% gain. The same pattern shows up over six months, with Ethereum up 17.80% versus Bitcoin’s 8.64%, showing Ethereum has been doing more of the catching up.
ChatGPT Predictions for Bitcoin and Ethereum by 2028?
ChatGPT’s two-year Bitcoin forecast puts the cryptocurrency at $120,000 to $150,000 by September 2028, compared with about $77,100 today. That would represent a gain of roughly 56% to 95%. The lower end would still leave Bitcoin below its $126,000 all-time high, while the $150,000 target would take it well above the previous record.
ChatGPT’s range assumes a successful crypto cycle, with continued institutional demand and broader market growth helping Bitcoin move higher. The forecast therefore leaves room for a meaningful recovery without assuming that Bitcoin will deliver an extreme rally.
For Ethereum, ChatGPT’s two-year forecast is $5,000 to $7,500 by September 2028, with $6,500 as its central estimate. From around $2,457, that would mean a gain of roughly 104% to 205%, taking ETH above its $4,953 all-time high. ChatGPT’s base case assumes stronger institutional adoption, continued ETF demand, growth in stablecoins and tokenised assets, and successful Ethereum upgrades.
The AI Agent’s more bullish scenarios put ETH at $8,000-$12,000, while an extreme bull case reaches $15,000 or more if Ethereum becomes a much larger part of global financial infrastructure.
ETF Flows Split the Two Cryptos
Bitcoin spot ETFs have brought in $320.71 million so far in September, a sharp drop from the $3.52 billion in net inflows recorded in August. The month also started with a setback, as Bitcoin ETFs lost $449.44 million in the week of September 10 after three straight weeks of inflow—$986.85 million on September 4, $924.48 million on August 28 and $1.92 billion on August 21. Bitcoin ETFs now have $55.17 billion in cumulative net inflows and $97.49 billion in total net assets.
Ethereum’s ETF market has cooled too, but from a smaller base. Ethereum spot ETFs have attracted $111.42 million so far in September, compared with $1.85 billion in August. They also turned negative in the latest week, with $19.30 million flowing out on September 10 after three consecutive weeks of inflows—$218.41 million, $824.42 million and $697.18 million. Cumulative net inflows now stand at $13.17 billion, while total net assets are $15.60 billion.
Ethereum’s ETF flows have slowed more than Bitcoin’s. Both markets have lost momentum, but Bitcoin has retained more recent ETF demand, giving it another edge in the two-year comparison.
Where Do They End Up in Two Years?
Bitcoin has the easier climb from here, and that advantage could matter more over two years than Ethereum’s stronger recent performance. Bitcoin needs a 63.4% gain to return to its $126,000 record, while Ethereum needs a 101.5% gain to reach $4,953. Ethereum’s 31.37% gain over the past month is impressive, but one strong month does not erase a recovery gap that large. ChatGPT’s two-year Bitcoin forecast of $120,000 to $150,000 also gives us a clear range to work with, while it did not provide a comparable two-year Ethereum target.
Two September events could set the tone for the next leg of the market. The Senate is scheduled to vote on cloture for the CLARITY Act on September 15, a procedural vote that requires 60 votes to end debate. The Federal Reserve is scheduled to announce its next interest-rate decision on September 16, with Polymarket pricing a rate hike at roughly 60% to 65% against a current upper bound of 3.75%.
If Bitcoin fails to break through $82,000 for a third time, near-term momentum could weaken, making the lower end of ChatGPT’s $120,000-$150,000 range more plausible over the longer term. Ethereum could also struggle to reclaim $4,953 if the broader market loses momentum, despite its stronger recent performance.
