Yes you have got the good point, vdice have to lower this down 0.22 at current exchange rate counts $20 which is really high minimum for players.
Also maximum bet for 19x multiplier is only 0.44 ETH which is very low limit compared to other normal bitcoin/altcoin dice sites.
Maybe they haven't taken the recent points into consideration to reduce the minimum bet amount. They should immediately do it otherwise they may lose a lot of smaller bets from many people. Including me, I don't want to bet so much of each game. It better to reduce as soon as possible.
Yes I also think they will loss so much players specially the one who like to give them a try for first time, as there is also no way to test their game without paying with real ETH and the minimum amount is quite high which new players don't want to use just to give it a try.
