Bitcoin Privacy: What Is Actually Missing?

Barry Silbert has said that 5–10% of capital currently held in Bitcoin could flow into privacy-focused cryptocurrencies over the next few years.

Statements like this always leave me puzzled. They seem to imply that Bitcoin has unresolved privacy issues.

It is not true. Bitcoin does not suffer from some inherent, unfixable privacy flaw. People who work closely with Bitcoin - Barry Silbert included - know this very well.

If you need to send bitcoin privately, you can use the Lightning Network. When someone exchanges bitcoin on rabbit.io and sends the funds to us via Lightning, we do not know - and cannot know - where those coins originally came from.

Of course, major industry figures are aware of this. But ordinary users who are less familiar with the technical details hear statements about capital "flowing from Bitcoin into anonymous coins" and may begin to assume that Bitcoin has a widely recognized privacy weakness. It does not.

That said, the Lightning Network does have one significant limitation: large payments can be difficult to route. I have sent 0.1 BTC many times without any issues. Larger amounts, however, have only gone through successfully on rare occasions.

Please keep this in mind if you are exchanging bitcoin via Lightning on rabbit.io. We impose no limits on our side, but the network itself has bandwidth constraints. Sending larger amounts can be frustrating. If you plan a bigger exchange, it is usually better to split it into several smaller transactions.

It is possible that Barry Silbert operates on a very different scale. For someone moving institutional-level capital, the ability to send only 0.1 BTC privately may feel equivalent to having no meaningful privacy option at all. In that context, his argument makes more sense.

But for most everyday users, the Lightning Network's capacity is more than sufficient.
