Is there a fixed supply of bitcoins around the wolrd or is it printable like $?
The fixed supply of the bitcoin was 21 million but in another calculation, the maximum supply of the bitcoin will be less than 21 million and why? due to the various reason just like hacked exchange site like mtgox.
And another personal case which makes the bitcoin loss in the wallet due to the forgetting their password or passphrase.
The supply of the bitcoin will not increase anymore.
