Who can burn the $BOB token
Anyone who owns BOB tokens in their personal wallet
Because the burning process is usually done by sending the token to the burn address (such as:
0x000000000000000000000000000000000000dEaD),
any token holder can burn their own tokens.
No one else can burn from other people's accounts
If you do not own the token in your wallet, you cannot burn it from someone else's wallet or directly from the market.
There is no contract owner who can enforce a burn
Because ownership of the BOB contract has been renounced,
therefore there is no person or team that can modify the contract to burn the token or enforce an automatic burn.
Summary:
Burning is only available to those who own the token, and no one can burn someone else's tokens or control the burn otherwise.
There is no automatic burn mechanism built into the BOB contract.
