In the contract `BetVerseToken`, the owner has authority over the following functions:
- `BetVerseToken.mint`: Mint tokens and increase the total supply of tokens
- `BetVerseToken.burn`: Burn tokens and decrease the total supply of tokens
- `BetVerseToken.setRatePerYearInWei`: Change the value of rate per year in wei
- `BetVerseToken.setForbiddenToStake`: Set the address forbidden to stake
- `BetVerseToken.setBurnableAddresses`: Set the address allowed to burn
- `OwnableUpgradeable.renounceOwnership`: Renounce ownership of the contract
- `OwnableUpgradeable.transferOwnership`: Transfer ownership of the contract

Any compromise to the owner account may allow a hacker to take advantage of this authority and mint any number of tokens to themselves or burn tokens from any users balance.

Centralization Related Risks in Contract `BetVerseToken`

The following functions are declared as `public`, contain array function arguments, and are not invoked in any of the contracts contained within the project's scope. The functions that are never called internally within the contract should have external visibility. 

Function Visibility Optimization

The function has a modifier `isNotEther` which prevents ether from being sent. However, this can be prevented by removing the `payable` function.

Unnecessary `payable` Modifier

Since the modifier checks whether `msg.sender` is allowed to call the `burn` function, the correct error message should be "This address is not allowed to burn". The current error message would imply that the tokens cannot be burnt from a certain address.

Incorrect Error Message

The function that affects the status of sensitive variables should emit events as notifications.
- `setRatePerYearInWei`
- `setForbiddenToStake`
- `setBurnableAddresses`
