Block enables 4 million merchants to accept Bitcoin payments: the payment narrative is shifting

A single tweet puts the “What is Bitcoin actually for?” debate on full display

@River said Square’s default enablement of Bitcoin payments for 4+ million U.S. merchants is an “omega-candle” moment. It’s not just a product announcement—it reignites the old question of whether Bitcoin is for storing or for spending. After @BitcoinMagazine and @TFTC21 retweeted it, the topic spread quickly, and with everyone’s recent concerns about traditional payment systems, attention shot up immediately.

On-chain data is fairly calm, though: TokenTerminal shows that daily active users after the announcement are still around 450k; circulating supply continues to slowly press toward 20.01M. Block’s Miles Suter called it “bitcoin as everyday money,” but Crypto Twitter immediately interpreted it as “mass adoption is about to happen”—ignoring that many merchants may simply never use the feature.

• Emotions race ahead of the details: Zero-fee Lightning integration gets wildly retweeted, but early discussions like the one by @SimplyBitcoin rarely mention how background liquidity is managed. If transaction volume suddenly spikes, clearing routes and channel capacity could run into problems.
• Huge differences in time expectations: Some funds treat it as a multi-year bet on Bitcoin’s dominance; Decrypt’s skeptics think regulatory uncertainty will slow merchant adoption.
• How to explain price volatility: Around the announcement, Bitcoin rose from 65.8k to 68.4k, up roughly 4% (Coingecko data), but looking at the trade structure, it looks more like institutions rebalancing than retail chasing hype (FOMO).

What truly matters: Block is launching it in a way that’s “enabled by default, turn it off if you want,” and merchants can switch to dollars immediately. This directly addresses the biggest obstacle—bitcoin price volatility being too high. Don’t expect an immediate surge in on-chain transactions—there’s no reliable data yet, and Cash App’s Bitcoin feature took several quarters to ramp as well. The point is: with no friction, millions of merchants can now accept Bitcoin payments, and market pricing hasn’t reflected this yet.

This price volatility isn’t the main point

Using the March 30 rally as “proof” that adoption logic has won doesn’t hold up. Price looks more like it’s moving with overall liquidity, and on-chain DAU hasn’t changed much. Chasing the rally is a trap. The real beneficiaries are the infrastructure builders and the patient holders—pricing benefits from network effects aren’t fully in place yet.

If disclosures keep coming and scale judgments stay consistent, I give 60–70% probability: by Q4 of 2026, we’ll see meaningful growth in merchant adoption—assuming that after fee waivers end, the fee rates are still acceptable.

A few takeaways:

• Merchants’ “instant switch to dollars” is the key mechanism—it solves volatility risk;
• Short-term on-chain activity and transaction volume may not rise, so watch it on a quarterly basis;
• Lightning liquidity is a potential bottleneck—route finding and channel management need engineering upgrades;
• Pricing favors infrastructure and long-term longs, and momentum trading doesn’t offer great value.

Conclusion: We’re still in the early days of the “payments” narrative. Infrastructure builders and long-term holders have the edge; short-term traders chase sentiment-driven volatility, and the risk/reward isn’t great.
