Do you know the number of wallets opened so far? Do we know the number of people using bitcoin?
Where can I get this information? Thank you.
The bitcoin network do not have a concept like open wallet action, all those wallet are already existed, you just randomly pick one and uses it.
also the address belongs to whom holds the private key, you can't owen a private key, you just hold it and nobody else have it.
here is a v2.5 of directory, you can check and get a good exam of "bitcoin wallet"
