Every day, people ask us: Why is Spark on Bitcoin? Why not just build another L1, L2? Why go through the hassle of bringing stablecoins onto Bitcoin?

The short answer: We’re Bitcoin pragmatists, not maximalists. Building a network is one of the hardest things in tech, and if you’re going to do it, you need every possible advantage on your side. Bitcoin provides that—here’s why.

​
1. Bitcoin is the only network with network effects

  • When building a network, distribution is everything. You can create the fastest, cheapest L1, but if you don’t have a way to get it into people’s hands, you lose.

  • Bitcoin has over 200 million users. You can send and receive Bitcoin using the largest wallets, banks, and neobanks today. Spark is instantly interoperable with hundreds of millions of endpoints.

​
2. Bitcoin is where the money is

  • For anyone building apps, you’re always wondering how you’ll get liquidity into your products. With Bitcoin, you don’t have to bootstrap liquidity — it’s already there.

  • Bitcoin holds 60% of all liquidity in crypto.

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

  • Most crypto tokens get flipped and dumped. Bitcoin is the only asset people want to stack long-term. Its scarcity and deflationary design make it a true digital gold.

  • As a builder, Bitcoin gives you an instant edge for rewards, retention, and engagement. No need to convince users — Bitcoin is what people already want. This opens the door for new product experiences like BTC cashback, yield, and incentives that feel more like stacking wealth than spending it.

​
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. Distribution and adoption are infinitely easier when you’re building on something people already trust.

​
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?

Think we’re wrong? Roast us. (Tweet or DM @buildonspark). Show us another chain that beats Bitcoin on all five of these dimensions. If you can, we’ll listen.
