Is it true,that whoever provides the digital signature is also the private key holder and the owner of the bitcoin address?

Not necessarily. It just proves the authenticity of the signed message.

The message content to sign should be given as a challenge to the person signing to prove ownership.

What do you mean not necessarily?

So leanmeabitcoin.com is wrong?

Blockchain is full of signed messages. You can pick any and try to claim that you own it.

But if they ask you to sign a challenge again you can't. Because you don't have the private key.

I believe CSW pulled a trick like this 😂

How do you sign it?

#[8] give python code for signing a message with Bitcoin private keys

What are block chain wallet ids?

What do they have to do with bitcoin wallets?

Thank you for clarifying...
