Earlier on Thursday, Bitcoin (BTC) slid below the psychologically important $80,000 price level. However, the ETF Flow Impact Score (EFIS) model suggests that the top cryptocurrency by market cap is heavily mispriced, at least 11 percent below its fair value.
EFIS model suggests heavy Bitcoin mispricing
A higher than anticipated U.S. Consumer Price Index (CPI) reading, coupled with brewing geopolitical tensions in the Middle East finally hit Bitcoin in the early hours of Thursday, as it fell below $80,000.
However, a proprietary price model called EFIS hints that BTC is likely 11 percent below where it should be. Essentially, the digital asset’s current fair value is around $88,144.
For the uninitiated, EFIS is a Bitcoin valuation model that measures how ETF inflows and outflows influence BTC’s fair value based on demand relative to total ETF assets under management (AUM).
In simple worlds, instead of tracking raw flow volume alone, the model uses AUM-normalized flows to estimate the structural price support created by institutional capital entering the market.
For example, when institutions like BlackRock or Fidelity deploy capital equivalent to even 0.1 percent of AUM daily, the compounding effect on cumulative normalized flow changes the structural price floor.
Since January 2024, Bitcoin ETFs have absorbed capital worth 1.394M BTC, representing a cumulative normalized inflow of 180.4 percent. This has developed a sort of gravitational support level that the current price has not caught up with yet.
Two possibilities for BTC
From its current position, there are two potential paths for BTC. The recovery thesis rests on the 30-day average flow rate which turned positive after a 4-month institutional withdrawal extending from November 2025 through April 2026.
The metric currently reads 0.096 percent of daily AUM. For BTC’s recovery to be confirmed, it needs to reclaim the EFIS-predicted fair price of $88,144. Above this price, the 1 standard deviation band at $105,572 will become the next macro resistance level.
On the flipside, if BTC fails to reclaim the $88,144 price target, then the next natural support level goes all the way down to $70,716.
Past data shows that BTC violated this EFIS-based floor price during the March 2026 capitulation event, and a second break through it would be structurally important.
