BitcoinHunt3r has already given an example above. $0.1 isn't a big deal here. I'm playing the crypto dice game at several casinos since last five years. Majority of the dice players hunt for big payout/multiplier. And most of them do pre-roll before setting higher base bet. Let's assume, you are looking for 990× multiplier at the dice game. There is a high chance to get longer losing streak. You have planned to do 500 pre-roll with the minimum bet limit. $0.1 will cost you $50 for the current min bet limit of Duelbits. The cost will reduce by 10 times if they set the min bet limit to $0.01.
