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.
Have been into this debate way before, but didn't get it considered yet by the management. I have been trying my best to take this to them and draw their attention towards this that the price of ETH has gone way above and losing such an amount would be harsh on our side, so they should really change the minimum to something which could be an affordable loss if lost so. So that we could gain more users for the site.
