@mk4 Please, why did you say bitcoin is psydonumouse? With what I know about bitcoin, it is not pseudonymous at all. It can be anonymous if you choose too. If you choose a verified wallet makes it to be non anonymous but there are many wallets like Trezor, Ledger Nano, coinomi, and many other wallets that do not even require you of email address and the anonymity remains the main goal.
Bitcoin is pseudonymous because there is no personal information attached to a Bitcoin address(though information can be affiliated with your address if you transacted with a centralized entity). Bitcoin is not anonymous because obviously, the blockchain is transparent hence we can visibly see every single transaction that occured in the network. Using non-custodial wallets only helps you become pseudonymous.
