No, I don't gamble with Bitcoin only. My favorite coin now is Dogecoin because it's not too expensive than bitcoin and I can use 0.001 bitcoin to buy a large amount of Dogecoin. With 0.001 btc, I can get almost 1995 Dogecoin which is enough for me to play any gambling games.
But sometimes, I used Bitcoin too, and I only want to spend my bitcoins in less than 0.001 btc. I am too afraid to lose much of bitcoin, and because of that, I prefer to use Dogecoin.
Besides of both Bitcoin and Dogecoin, I use Verge but not much gambling websites were accepting Verge, and it's for a long time ago since then I moved to use Dogecoin.
There is a lot of gamblers use Dogecoin instead of bitcoin, I was really confused about that in the past, but when I tried to gamble using dogecoin, I felt it's more funny and good, mostly for people who don't want to lose a lot of money! I mean for gambler who play just for fun and not for profit.
I mean if you lose 1000 dogecoin you will not get depressed because it's not so much money, but if you play using bitcoin and you bet with more than 0.01 btc, you'll afraid a bit even if the bet is easy, because 0.01 or even more it's not such a few dollars, so in my opinion, dogecoin is a very good crypto for gambling.
