Monero has a blockchain which anyone can view. But that doesn't mean that you can see what happens inside of it, so to call it "public" is misleading since any details about the blockchain are private. Nobody can see account balances or transaction activity. To call it public is like saying that I know everything that's in a house because I can see the house from the street, even though I can see nothing inside of it.

Here's my address if anyone wants to try and trace any of my payments, or see my balance:

As I put in my link in the previous post to StackExchange, there are additional steps one must take in order to use Blackbytes and that opens them to risk. With Monero, privacy is by default.
