how much data represents 1 satoshi? and on entire bitcoin I mean, how many bits or bytes represents 1 satoshi, the minimun bitcoin portion
and how many bytes represents one entire bitcoin, not a block, a 1.00000000BTC
Bitcoin amount is simply a number in the outputs of transactions, bitcoins themselves don't really exist. For example, in this transaction, there is this output:


  "addr":"1P3VQasrhmCnViL4sVouxSZiSu1BRWuCvN",
           "value":6103964


Value is the number of satoshis in the output, these output values are the only representation of bitcoins on the blockchain.
