BitDice has been one of the biggest online crypto casinos during last several years.
It has been one of the most reputable sites, too. Additionally, BitDice has run its promotions via signature campaigns for years, and their participants have not complained about payments.
In general, I don't see risks with BitDice, so simply ask for support if you got troubles and need help.
Bitdice reputation's speak for itself, no accusations and having a successful ICO in 2017.
Overall what you have said is true and they keep on doing their best to satisfy its customer here, by giving out the promotions and really huge max bet, it is been great to play on this site and I can say they have really successful ICO and I believe they are the first site that using this kind of payment to substitute the faucet type so it is really good
