Hello guys..
Yesterday I was sign up for my new Bitcoin wallet.
This wallet only need your nickname/username for transfer within same wallet users.
After every transaction, the wallet automatic add the name to your address book.
You can transfer as low 1 sat and user to user transactions are free and have no transaction fee.
They are also instant, with no confirmation delays. It's the best value!
And very simple.
Get one & try by yourself. Sign up your wallet here
