There is nothing we ignore.
Cold storage?

Liars. Go fuck yourself.
and the falsified logs with the before and after balance being exactly the same
Falsified logs ?!
We already mentioned above what the start_balance and end_balance means, but lets do it one more time with an example...
EXAMPLE:
newalias has balance of 1.1 BTC
newalias bets 0.1BTC on this spin
newalias loses the bet.
The above EXAMPLE will have this round log:
{
"round_id" : "ROUND_ID",
"time" : "DATE",
"bet" : 100.00,
"win" : 0.00000000,
"start_balance" : 1000.00000000,
"end_balance" : 1000.00000000
},
In case you missed it, the above values are in mBTC.
1BTC=1000mbtc
0.1BTC=100mbtc
START_BALANCE is the balance AFTER the wager.
END_BALANCE is the balance AFTER the win.
