Doge coin was the great after Ripple for gambling, because of the low-transaction fee and also the speed transaction between each wallet can be a quick one. I don't really care about the value within these coins, because of really cheap to buy for 1 coin, so you can play or maybe using safest strategy, or just testing some games.
the most use on betting would be ripple and doge but for me my most use coin was btc only . idk why but i always prefer btc among the other coin even if the site accepts several altcoins .
maybe because im more familiar with the value of btc . i dont need to use crypto calculators when doing bets ( small or big ) . i dont also have a problem on withdrawal and depositing speed because i can always wait .
