I have now account in PrimeDice and also in bustadice but i can't play due to empty balance, i encountered gambling site that have a faucet that you may claim this if your balance is empty then start again betting with 10 satoshi's free and it is PrimeDice. But mostly in gambling site now sadly there's no faucet due to high transaction fee of bitcoin. The suggestion of other gamblers now was right i think much better they used altcoins aside from bitcoin in betting of gambling site and for having a faucet because altcoins lower fees than bitcoin.
