i'm player of Primdice more than 5 years and I really satisfied using of this, Im happy that this gambling sites are reached 80 billion bets and it is one of the highest numbers of bets in the crypto online gambling. Also this gambling sites are helping for the dogecoin to rise the value.
They help make the name for DOGE and similar coins that have been a part of the legacy cryptocurrency group but to rise in value - I doubt that.
When a coupon loaded with DOGE comes into offering people are going to go for the free money and eventually lose it on the casino. They are then going to go with buying DOGE and spending more DOGE on the casino - you might argue that I am contradicting my opinion about raising the value of DOGE by this but it is less significant that what celebs like Musk have already done. Gamblers being impulsive will spent bought coins immediately and therefore the casino will profit.
Actually the coupon can be claimed in any coin you wish as the email also mentioned and doge coin was just their suggestion because of the recent pump like you said forced and supported by Elon musk. I haven't reached the highest levels yet so I got reloads and the value is decent but not crazy and I am just trying to hit some big multiplier with them.
For some reason I only love playing dice at PrimeDice even though I bet for sports at stake but when I really feel like rolling dice and doing a session then I just deposit into Primedice because the betting is faster, I have felt and there is just a home feeling maybe because I have been on Primedice since their v2 I think.
