Increasing the minimum bet might be a service for bitcoin as a whole. There'll be less satoshdicedust to bloat the blockchain.
what differance does it make if it bloats the block chain .. there is a reason why we pay transaction fee's what do you think will happen when there is no longer any rewards per block ?
I admit i may have had part in messing with satoshidice inadvertently by place 2000 or so bets it .001 plus using the martingale style strat was doing pretty damn good to right up until i walked away from the computer and the min's went up and i got raped over and over and over again on transaction fee's and returned bets
