That is very true and I can totally understand your decision. I was very skeptical too at first, before I found EpicDice. I cannot guarantee anything, but I don't think that they will leave, and legit gambling dApps, which both EpicDice and KG seems to be (based on how long they've been around, updates and all that), is good for Steem. Well, that's my opinion obviously.

That being said, gambling, or gambling tokens etc, aren't for everyone, and I can totally understand that. I usually don't recommend gambling dApps, but I do write about them. Especially EpicDice, as I am a moderator of their discord channel and a believer in the project. :)
