We get this question a lot: why build Spark on Bitcoin? Why not launch a new L1 or L2? Why take on the challenge of bringing stablecoins to Bitcoin?

The short answer: we’re Bitcoin pragmatists, not maximalists. Building a network is one of the hardest things you can do, and if you’re going to do it, you need every structural advantage on your side. Bitcoin gives us that—here’s why.

​
1. Bitcoin is the only network with network effects

In crypto, distribution is everything. You can build the fastest, cheapest L1, but if you can’t get it into people’s hands, it doesn’t matter.

Bitcoin has over 200 million users. It’s natively integrated into the largest wallets, banks, and fintech apps. That means Spark is instantly interoperable with hundreds of millions of endpoints from day one.

​
2. Bitcoin is where the money is

Liquidity is the lifeblood of any financial network. If you’re building in crypto, you need to bootstrap liquidity before your network can take off.

With Bitcoin, that problem is already solved — 60% of all crypto liquidity is sitting in BTC.

​
3. People actually want to accumulate Bitcoin, not sell it

Most crypto tokens get farmed, dumped, and forgotten. Bitcoin is different—people stack it, not sell it. It’s scarce, it’s deflationary, and it has the strongest digital gold thesis.

For builders, this is amazing. Bitcoin gives you an instant edge for rewards, retention, and engagement. No need to convince users—it’s already the asset they want. That unlocks entirely new product experiences, like BTC-based yield, cashback, and incentives that feel like wealth accumulation rather than just another points system.

​
4. Bitcoin is the only crypto your grandmother has heard of

Ask your grandmother if she’s heard of Bitcoin. Now ask her about any other crypto project.

This matters. When you build on Bitcoin, you’re not starting from scratch—you’re tapping into the only crypto brand with mainstream trust and recognition.

​
5. Bitcoin is the only network that will outlive every timeline

In 1 year, 5 years, 10 years, 50 years, or even 100 years, Bitcoin will still be running. Can you confidently say the same for other scaling solutions?

As a builder, do you want to wake up one day and realize that all the liquidity your users rely on is at risk of disappearing?
