Slow grind down, but not a collapse — Reconstructing BTC's cost basis under panic through URPD
On Feb 4, BTC dropped from the Jan 15 high of $97,000 to $73,000. The speed and depth of this dump instantly crushed the optimism that thought $80k would hold. Let’s be real, if you say there’s no panic, you’re lying. So, it’s worth reviewing what happened to BTC’s cost basis during this period and what key signals are hidden beneath the surface.
To make things easier, I pulled the full URPD data and charted it by $10,000 intervals. This lets us clearly track how coins moved and gauge the current market sentiment and behavior. (See Chart 1)
From Jan 15 to Feb 4, the number of profitable coins below the price dropped by 67,008 BTC (9.7% of the total decrease), while the underwater coins above the price dropped by 611,324 BTC (88% of the total decrease).
What does this mean? Basically, long-term holders with unrealized gains are selling less and less as prices fall. Either they think there’s no point in taking profit here, or they just DGAF about price and hold long-term. Bottom line: the lower we go, the less these guys sell.
The main selling pressure comes from bagholders up top. Over 600k BTC got flushed out in just 20 days — that’s how intense the panic-driven capitulation has been.
But on the flip side, we’re seeing massive bids in the $80k-$90k and $70k-$80k zones. Especially the latter, with net buys of 450,413 BTC — almost double the previous range.
This shows there’s big money lurking, stepping in hard with real conviction — “You dump, I buy. The lower it goes, the more I scoop.” That’s what makes this cycle fundamentally different from previous ones.
Even if the 4-year cycle theory hasn’t been disproven, bulls are defending every drop. 100k, 90k, 80k, 70k… the cost basis is shifting lower in steps, not falling off a cliff.
Lots of people are calling for this cycle’s bear bottom at $50k or even $30k. I’m not so sure. What I do believe is: once bears squeeze bulls to the absolute limit and supply dries up, a full-on bull counterattack is inevitable.

I’ll leave you with a question to chew on:
On the chart, the total coin count was 16,184,047 on Jan 15, 2026, and 16,198,235 on Feb 4 — a difference of 14,188 BTC. Where did it come from? What does it mean? Drop your thoughts in the comments and let’s discuss!
