Yeah this is the thing isn't it, how many hoops do you want to have to start jumping through just to play some games online? I know it's not 3Dice's fault that they're basically crypto only now (certainly they're the only deposit options I can see there), but it does create something of a barrier to entry. This is partly why I tried to leave balances rolling over from one month to the next in my Personal Safe, but unfortunately Dice Fusion put an end to that this month
Getting everything set up at Coinbase in the first place was quite a long-winded process, in fairness it all went fine but there were a lot of stages to it, identity verification and all that jazz - I'm not sure I can be arsed doing it all again somewhere else, especially as I might find my card gets declined at the end of it all anyway!
I've used the same card many times at Unibet as well, and now all of a sudden it gets declined there too, but works fine at Tombola
Back to crypto, I have literally zero interest in it as a currency/investment/whatever, it was simply just a way to enable me to carry on playing at 3Dice once the last other option that was available to me there (EcoPayz) disappeared.
I remember back in 2012 I could just deposit there directly using a standard UK credit card
