So you risk 1000btc on a dice site to win 5000 satoshi? You better make sure they are very very legit because most of them would be gone. Who is going to control 1 sat bets with 1000btc back lol. Not happening and the OP did clearly say he had 0.2btc to work with. He could do similar and bet 98% get the riches 5000sat and run but pretty sure he is looking to turn his 0.2btc into a 1btc-100btc.
