I still get asked, “What if a better Bitcoin comes along?”

But the truth is, dozens of “better” Bitcoins have already come.

The code Satoshi wrote has already been heavily modified, and it will continue to evolve.

In a sense, we may already be using the 28th successor to Bitcoin—and most people just call it “Bitcoin.”

A more accurate way to put it is this:

We call “Bitcoin” the chain that the majority of people recognize and collectively maintain.

So it’s not that a second Bitcoin is impossible—it’s that any future version will still have to acknowledge and preserve the existing ledger.

That’s the real explanation.
