Bitcoin just took a massive leap toward mainstream adoption.

Square, the payments giant behind Cash App, has officially activated Bitcoin payments for 4 million U.S. merchants— and they’re waiving all processing fees through 2027.

Here’s what that means: any small business using Square can now accept BTC directly through the Lightning Network, with transactions settling instantly in either Bitcoin or U.S. dollars. Merchants can even choose to keep a percentage of their sales in BTC for long-term holdings — up to 50% automatically converted each day.

That’s huge. 💥

For years, crypto fans have dreamed of paying for coffee, clothes, or concert tickets in Bitcoin — without friction or fees. Now, it’s reality.

According to Square’s internal survey:

• 29% of businesses are exploring Bitcoin conversions, and

• 89% of those plan to accumulate BTC long-term.

This isn’t just a payments update — it’s a monetary mindset shift. Businesses are moving from “accepting crypto” to stacking it as a treasury asset.

And it’s all powered by Lightning Network integration — making payments faster, cheaper, and more efficient than traditional card rails.

With Bitcoin prices hovering near six figures, Square’s move could trigger a second wave of adoption across retail and fintech — especially if competitors like Stripe or PayPal follow suit.

The takeaway? Bitcoin is no longer an investment side-quest.

It’s officially a business tool — and that’s bullish for everyone.
