I have done very well investing in BTC casinos. Just-Dice is my favorite, although you do have to convert to clams. Yolodice has been legit and lets you do 10x leverage. I recommend SafeDice for people holding XMR. Checking out BitDice as they are having an ICO soon. Thanks!
In above sites you mentioned bitdice is good invest for dice or casino games. Being out of gambling playform. I can say any type of gambling option would waste your money. If you enough fund you can at least donate to the poors. For entertainment you prefer betting to see profit some time.
It looks you wrongly understood above post because OP is talking about bankroll investments not gambling on those sites. He has just shared his experience as bankroll investor of those sites. Everyone knows that gambling is very risky and can lose money in it but they just want to try their luck with a small amount and get some fun at the same time. Gambling is good only if you play for fun but if you want to make money from it then you will not enjoy games and mostly never win money in the long run.
this thread is about investing in casinos bankroll which is profitable in most cases
not about gambling,gambling is based on luck and chance,you are expected to be losing in the long run
minimum 1% house edge,add to that suboptimal bank handling and poor strategies and you wil lsee that most of the gamblers are losing money
consistently,thus making investments more and more viable way of storing your coins
