Gambling is NOT a good way to get rich with Bitcoin, unless you are extremely lucky. There are only a few people that got rich from gambling, and in the long run you will get bankrupt. I would just wait and try getting more and more satoshis. Soon, the price will shoot up. And "soon" doesn't mean tomorrow. I'm talking about between half an year and an year.

I don't know man; sometimes people lose their money because their greedy. You just gotta be patient and think smart sometimes. I posted a pic of how i do my daily gamble using only 0.001BTC; most of the times i make profit, if you remain patient you can get alot sooner that you think.
each of these methods are only good as long as you can ALWAYS win and make profit with them. so in case of gambling since you can't do that then it is not a good way of making profit and getting rich eventually. and martingale method that you are using here is one of the ways that is proven to be bad because of the bust out you encounter after a short while.
You don't need to "ALWAYS" win when it comes to gambling; like i said you have to be
patient and avoid being greedy; plan your income wisely and know how much you can afford to lose. For example since i'm a member rank on this forum i can get a max of 260'000satoshi from posts each day. I use 100'000satoshi(0.001BTC) from that each day to gamble. Just by doing that i have actually gotten more than i get from just doing signature campaign.
Heres an updated image of the picture i posted earlier.

Its been 8000+ rolls so far and you can see that i've made a profit. When the value reachs 800'000satoshi; i withdraw 500'000 and let it continue on auto roll.
I think this is still not recommended for those who planning to become rich.. gambling made only to give entertainment for people you will not rich is those game. unless if you are buying ticket in lottery with high jackpot prize pool.. If you want to rich i think its the best to invest for your knowledge do study and learn something online like making a website and look for a whitehat methods which is making your own site that you can make money just to update it every day..
Most successful online are bloggers which is earning passively just making a good article and put some advertisement in their blog.
Better to stay away in any gamble site if you don't want to lose your money..
