Ok.
Why wouldn't I get random numbers? If anyone does not believe this I can make a video.
On the second quote - fixed.
On the third - this was made to make sure that only known people on the forum will be able to gamble - I mean I will not be able to create fake accounts and cheat.
You don't make a video. Let's do this:
http://www.xorbin.com/tools/sha256-hash-calculatorI have a secret. My secret has a hash of 37ac021f55a15b71fe3756163421509fbaa4a300e7857d44a894a0a363c67c4d
You create a secret (enter something unique into the data box). You post the hash power.
We decide the winner by combining both of our secrets (not the hash, but the actual underlying secret) and getting the first digit from the hash.
Pick a secret. Or not, because this is a silly idea. I bet 100 BTC, others bet a total of 0.05 btc, you're not going to pay me out 300 btc.
I made that easier. Please note that I fixed the bet amount.
