This week I actually tripled some of my SBD, I came across a website called luckygames.io , (this is my referral link, if you don't want to use it you can use this) link it is an online casino which lets you play games such as dice. But this casino only uses altcoins. It has a large variety of altcoins(53!) you can use, even STEEM and SBD!, I have tried the depositing and withdrawing and can assure you that it works. If something goes wrong there is even luckygames support that will give you your funds back if you provide sufficient evidence! I do not encourage gambling and will definitely recommend only putting in what you can afford to lose as there is a chance that you will lose everything, that said there are various techniques online which can increase your chances to win at the games. One of these techniques is called the Martingale technique, I used this technique myself and it worked for me. I didn't send too much as I don't want to lose everything but I'm planning depositing more in the future now I know everything works.

How the Martingale strategy works:
After you deposited your desired altcoin you can start playing, I used the Martingale strategy for dice.
You start by placing a small bet, I chose the odds as close to 50% as possible (you can change the percentage of you winning, the smaller the percentage the greater your payout will be) every time you lose you double your bet, for example if I start with a bid of 1 dogecoin and I lose I will bid 2 dogecoin next round, if you lose again you bid 4 dogecoin next round and so forth. If you win your bet you will go back to your starting bet. For me this strategy worked but there are lots of strategies on the internet, or you could just go with your gut.

I hope you have fun and wish you all good luck if you decide to play!
