Why drops and recoveries are not symmetric
After a 30% drop, 70% of the value remains. To get from 70% back to 100%, you must add 30 points on top of that 70%, i.e. 30 ÷ 70 ≈ 42.86%.
The deeper the drop, the faster the required gain climbs — a pure consequence of ratios, independent of the asset.
Using the reference price
With 2,471 USDT as the reference price: a 30% drop takes the price to about 1,729.70 USDT; to return to 2,471 USDT it must rise 42.86% from 1,729.70, landing exactly at 2,471.00 USDT.
So a 30% drop corresponds to a 42.86% recovery — the two are not symmetric.
Drop levels compared
| Drop | Required gain |
|---|---|
| −10% | about +11.11% |
| −20% | +25.00% |
| −30% | about +42.86% |
| −40% | about +66.67% |
| −50% | +100% (a double) |
Pure arithmetic, excluding fees and slippage.
Notes
This is arithmetic only. With fees and slippage, the required gain is higher still.
The required gain says how much the price must rise, not whether it will — this page makes no market call.
FAQ
ETH drops 30% — how far must it rise back to 2,471?
From about 1,729.70 USDT it must rise about 42.86% to reach 2,471.00 USDT. The formula is 30% ÷ (1 − 30%) ≈ 42.86%.
Why does a 50% drop need a 100% rise?
2,471 falling 50% leaves 1,235.50; getting from 1,235.50 back to 2,471 needs +1,235.50, which is +100% relative to the smaller base of 1,235.50.
Does this apply to every coin?
Yes. It depends only on price ratios, independent of the asset or its price level.
