Bitcoin bull market call looks premature as capital keeps leaving, even with $90K chart setup in play

On-chain data from Glassnode shows new capital is still leaving the market, Europe’s answer to Michael Saylor’s Strategy is running up against structural constraints its US counterpart never faced, and at Paris Blockchain Week 2026 the industry has spent more time debating the quantum horizon than the next leg up. For anyone looking to call a new Bitcoin bull market in April 2026, the signal remains firmly amber.

Price action flatters a market that is still bleeding capital

BTC’s rally above $76,000 on 15 April briefly revived the bull-market chatter. Analysts at Glassnode were quick to push back. On-chain researcher CryptoVizArt, using the firm’s “true market mean” (TMM) metric — a cost basis estimate that filters out inactive and lost coins — noted that Bitcoin had been trading below the average active investor’s entry level for 75 consecutive days as of mid-April.

That is a meaningful stretch, but not yet a cycle-defining one. Historically, similar breaks below TMM have lasted anywhere from two days to more than 11 months, with the deepest drawdowns of the 2018–19 and 2022–23 bears reaching 57%. “75 days is still early,” CryptoVizArt wrote on X. “The 2018 and 2022 episodes didn’t bottom until months 5–9. The signal isn’t ‘all clear’ — it’s watch closely.” Glassnode’s TMM currently sits near $78,000, and reclaiming that level is what separates a relief rally from a trend change.

The capital flow picture is arguably more revealing. Independent researcher Axel Adler Jr. points out that Bitcoin’s 365-day market cap growth rate relative to realised cap has been negative for every trading day of 2026 so far — 105 sessions and counting. Realised cap itself has fallen from roughly $1.12 trillion at the start of the year to about $1.08 trillion, a 3.2% decline that reflects net capital exiting rather than entering. The 30-day realised cap change has improved off early-April lows near -0.54% to around -0.32%, but remains in outflow territory.

Put plainly: the market is not attracting enough fresh money to sustain higher prices. The recent bounce is a slowdown in selling, not a wave of new buying. Is it time to buy Bitcoin? Soon, perhaps.

The bulls still have a chart, and an on-chain tailwind

None of this means the bull thesis is dead. Technical analysts have been quick to note that BTC’s move above $76,000 validated an ascending triangle breakout, projecting a measured move toward roughly $89,050 — an 18% upside from current levels. The daily RSI has climbed to 63 from the oversold 15 print on 6 February, and a sustained close above the convergent 100-day moving averages near $75,000 would open a path to the psychological $80,000 level before any $90K test.

There is also a legitimate on-chain counterweight to Adler’s capital-flow caution. Bitcoin’s daily transaction count hit roughly 765,000 on 5 April, a 62% jump year-to-date and the highest reading in 17 months. “$BTC daily transaction count is higher than when $BTC was $120K,” analyst CW8900 observed on X. “The network is showing bull market behaviour.” Total network fees have also ticked up around 4% week-on-week, which Glassnode frames as an uptick in willingness to pay for block space — a classic sign of returning demand.

The tension is clear. Transaction activity and chart structure look bullish; realised cap and TMM say the marginal buyer has not yet shown up in size. Both can be true. The 2019 and early 2023 analogues saw exactly this sort of divergence resolve bullishly only after several more months of grinding.

Europe’s treasury playbook won’t be a carbon copy of Strategy

While traders debate the next candle, a quieter structural story is playing out on corporate balance sheets — and the framing matters for any bull thesis that leans on treasury demand. At Paris Blockchain Week 2026, executives made clear that Europe’s emerging Bitcoin treasury companies are not going to mirror Saylor’s US model.

Thomas Vogel, a partner in the Paris and Frankfurt offices of Latham & Watkins, pointed directly to the mechanics. “If you issue convertibles in the US, the constraints are not the same as when you issue them out of a French balance sheet or a balance sheet in Europe,” he said, citing differences in market depth, regulation and investor behaviour. Alexandre Laizet, who leads Bitcoin strategy at France-based Capital B, said European firms are leaning on local market infrastructure — French public listings and Luxembourg-based vehicles — rather than replicating Strategy’s convertible-heavy US template.

The scale gap is already visible. Per BitcoinTreasuries data, Germany’s Bitcoin Group SE holds 3,605 BTC; Capital B holds 2,925 BTC at an average cost of $99,932 — a roughly 26% unrealised loss at current prices. Netherlands-based Treasury holds 1,111 BTC at an average of $111,857 (around 34% underwater), and Sweden’s H100 Group sits on 1,051 BTC at $114,615 average cost. Against that, Strategy alone added 13,927 BTC in a single week in early April to push its total stash past 780,000 BTC, acquired for a cumulative $59 billion. The European cohort is, in aggregate, closer to a rounding error on Strategy’s balance sheet.

The practical upshot for the market: if part of the 2024–25 demand base was a US-style, capital-markets-driven corporate bid, Europe is unlikely to plug the gap quickly. Shallower capital markets, tighter prudential rules and the in-flight MiCA 2 regulatory review all cut against rapid convertible-fuelled accumulation. European treasury demand will grow, but it is going to grow in a different shape, and at a different speed, than the US playbook that defined the last cycle.

Adam Back drags quantum back into the conversation

The third strand of this week’s narrative comes from an unlikely corner for a bull-market debate: cryptography. Speaking at Paris Blockchain Week, Blockstream CEO Adam Back — one of the few people whose work predates Bitcoin itself — argued that Bitcoiners should be preparing for quantum computing now, even though the threat remains, in his words, two to four decades away.

“Quantum computing still has a lot to prove. Current systems are essentially lab experiments,” Back said. “That said, Bitcoin should prepare.” His argument is pragmatic: the safest route is to build optional, backwards-compatible upgrades — hash-based signatures, Taproot-enabled alternative signature schemes — before they are urgently needed. Blockstream has already implemented hash-based signatures on its Liquid Network layer-2 as a live testbed.

Back went further in a second session, suggesting that a future post-quantum migration could inadvertently clarify the true size of Satoshi Nakamoto’s holdings, estimated at between 500,000 and 1 million BTC. Any holder wishing to secure vulnerable coins against a future quantum attack would need to move them to a new address format; coins left unmoved could reasonably be treated as lost.

That comment landed in the middle of a live and increasingly fractious debate. On 14 April, Bitcoin developer Jameson Lopp and five co-authors published BIP-361, proposing to freeze quantum-vulnerable coins — Satoshi’s stash included — to prevent theft once cryptographically relevant quantum machines arrive. The backlash was immediate. Developer Mark Erhardt branded it “authoritarian and confiscatory,” while Metaplanet’s Phil Geiger framed it more sharply: “We have to steal people’s money to prevent their money from being stolen.”

The quantum question is unlikely to move the price in 2026. But as Brave New Coin laid out in March, the real asymmetry is not whether the threat is imminent — it is that Bitcoin upgrades take 5-10 years to coordinate, while quantum hardware progress is nonlinear. Google and Caltech researchers warned in March that far less computing power may be needed to break elliptic-curve cryptography than previously modelled. Back’s own position — that developers would “act quickly” if the threat arrived sooner, because “bugs have been identified and fixed within hours” when urgent — is reassuring only to the extent you trust a contentious community to reach consensus under pressure.

What to watch from here

Putting the three threads together, the honest read on Bitcoin in mid-April 2026 is that the recent bounce is encouraging but unconfirmed. The price is below the true market mean, realised cap is still falling, US treasury demand has narrowed to essentially one buyer, Europe’s cohort is structurally smaller than many expected, and the developer community is simultaneously trying to plan a decade-plus cryptographic migration without a consensus on whose coins can be touched.

Three things would materially change the picture. First, a sustained reclaim of the $78,000 TMM alongside the 30-day realised cap change turning positive for a run of sessions — that would be the cleanest signal that new capital is genuinely re-entering. Second, a broader European or Asian corporate treasury wave at scale, beyond the current Capital B / Bitcoin Group SE cohort, which would diversify the institutional bid away from Strategy’s dominance. Third, a credible roadmap on post-quantum migration that doesn’t require freezing dormant coins — the Blockstream hash-based signature work is the most promising candidate to date.

Until at least one of those lands, the bull-market call remains exactly what CryptoVizArt described: not “all clear” — watch closely.
