To average and casual gamblers I don't think this kind of reward is important as they are not heavy bettors.These rewards are created exactly for these high rollers and not for the average gamblers.
On some gambling websites it's really not only for the high rollers.
I mean, on Bitsler for example, you can already level up and open loot chests when you've wagered a couple of hundred dollars worth of cryptocurrency.
Same with other websites & keep in mind, if you play dice at a 1.02 multiplier, you can get there quite fast.
