I am using freebitco.in since couple of years and trying to roll almost every day. But never won something big. I spent more than what i earned from free roll or multi. Spent few dollars on jackpot. But either its my luck or i have got bad client seed every time.
it hurts a lot to be losing every day, Is frustrating. I remember that I never won, I watched videos on youtube about the strategies to win the HI - LO game, I spent hours on it and in the end I ended up losing... funny Is that I I lost every satoshi I spent days collecting, imagine spending many days collecting satoshi and then playing and losing, it was very frustrating. there was one time I collected a lot of satoshis from various sites and I went to play and lost. then i decided to stop, this was my total deposit "0.011 btc" it was all thanks to faucets and i lost miserably
You should educate yourself more on this matter if you really thought you could win something on the long run with some strategies on this kind of games. Videos and tutorials about strategies in pure games of chance are scams, the only way to win in this kind of games is to be lucky. Otherwise on the average you will lose the casino hedge like most players (not all of them, but most of them).
