Token Access Issue

In the source code from etherscan you can see that total supply and initial balance are not assigbed the same value.

function Bitscoin(
    ) {
    balances[msg.sender] = 2000000000000;               // Give the creator all initial tokens (100000 for example)
    totalSupply = 20000000000000;                        // Update total supply (100000 for example)
    name = "Bitscoin";                                   // Set the name for display purposes
    decimals = 4;                            // Amount of decimals for display purposes
    symbol = "BTCX";                               // Set the symbol for display purposes
}

The difference is a zero.

• balances = 2000000000000
• totalSupply = 20000000000000

So 90% of the total supply is unassigned.

Note: The contract doesn't have a mechanism to increase an existing account balance.

Check where and how much you minted tokens. Note: it's better to attach the token address for more info.
