no you will lose trust me
The house edge in most dice games is 1%. It's possible to win in the short term.
Dice games will scam you
That's unlikely. Just-Dice.com absolutely won't scam you. It will offer you 1% less than true odds on every roll. If that's a scam then they scam you, but other than that it's provably fair.
Last night while I was sleeping someone won over 2700 BTC on Just-Dice, taking the house profit from over 2000 BTC to under -700 BTC. That's a profit for the player of over $250,000 in just a few hours of play.
Now tell me that the site's a scam! The winning player was able to withdraw his winnings just as soon as I was grabbed them from the secure offline Bitcoin wallet.
