You are right! It's my fault, it's definitely SHA256 of the hex representation of the server secret. SHA512 would be an overkill. My mistake.

I have tipped your YD account 0.01 BTC. Thanks for reading through the FAQ and having a critical look at YOLOdice!

I know you might see it as a conflict of interests, but I highly encourage you to keep an eye on YD. I would be more than happy if you invested in YD some day too :-)

Thanks for the tip. Now I can get to work on repairing my chart. I was doing so well, turning a 1,500 satoshi faucet drip into 222,222 satoshis at one point, but then lost it all trying to hit a 0.1% bet:



I revealed my server seed to verify the rolls. I eventually got it to verify, but it's weird how you use the server seed in its binary form for the HMAC, but in hex form for the SHA256 hashing.

In my javascript roll verifier I had to add code like this to convert the secret as given by the site (a hex string) to a binary format:

Code:
bytes = [];
for (i = 0; i < secret.length - 1; i += 2)
    bytes.push(parseInt(secret.substr(i, 2), 16));
secret = String.fromCharCode.apply(String, bytes);

OK, the most obvious error I found was where the FAQ says:



The server seed hash is only 64 hex characters, or 256 bits. I verified that it is an SHA256 hash of the server seed, not SHA512.

My user_id is 113.

On the other hand, JD's "off-site investment" can also be used as leverage in exactly the same way as our leverage.

Yes, in fact I wrote words saying just that:

So your "leverage" is exactly the same as Just-Dice's "offsite investment" feature, rather than true leverage. The "loan" amount (or "offsite amount" in JD terms) is constant and doesn't grow or shrink as people play.

My complaint is only in the words you use. "Deposited" isn't how much people deposited.. "In the bank" doesn't show how much is in the bank. Etc.:

[Edit: I guess that also means the "Deposited" column doesn't show how much the investors deposited, but rather shows how much they have now. And the "In the bank" statistic doesn't show how much is in the bank, or how much is available to be won because most of it is made up of coins which don't actually exist (and were 'loaned' into existence). The same goes for the "over 226BTC already invested" - most of that isn't real coins, but the result of pretend loans. Right?]

Do you pay bug bounties at all? I didn't find a way of cheating, but I did find some factual errors in the FAQ.

Yes, definitely! Site's profit is not stellar yet, but I try my best!

I don't think that's true. You would only need to recalculate the share for each investment tier, ie. 10 numbers.

Yes, you are right. Still, this involves floating-point calculations every single bet. This probably could be optimized, but from experience - floating-point rounding errors tend to accumulate. With fixed per-investment shares you only do floating-point operations when investments are opened/closed/commission is taken. Other than that we do all balance operations on integers.

There might be a way to do this better, but I decided to do it the simple way, avoiding potential issues.

So your "leverage" is exactly the same as Just-Dice's "offsite investment" feature, rather than true leverage. The "loan" amount (or "offsite amount" in JD terms) is constant and doesn't grow or shrink as people play.

Indeed, it does not grow or shrink. But it's not uncommon in the financial markets to use "investment with leverage" where the loan is constant. Take Forex for example.


[Edit: I guess that also means the "Deposited" column doesn't show how much the investors deposited, but rather shows how much they have now. And the "In the bank" statistic doesn't show how much is in the bank, or how much is available to be won because most of it is made up of coins which don't actually exist (and were 'loaned' into existence). The same goes for the "over 226BTC already invested" - most of that isn't real coins, but the result of pretend loans. Right?]

Initially I thought it was a good idea to show "leveraged bankroll" by default, but I have to agree with you. It's misleading and people keep asking about it. It's almost decided we will change the way bankroll is presented, hopefully avoiding the confusion :-)

On the other hand, JD's "off-site investment" can also be used as leverage in exactly the same way as our leverage. People could declare their off-site coins just to have a larger stake in site profit since they do not need to prove they actually have them. Am I right? Are you showing only on-site coins in bankroll? Sorry for my ignorance, I am really curious and I haven't found it in your FAQ.

Edit: OK, so you are showing only on-site bankroll. Max profit is 0.5% of the effective bankroll. I did the math.

Do you pay bug bounties at all? I didn't find a way of cheating, but I did find some factual errors in the FAQ.

Yes, definitely! Site's profit is not stellar yet, but I try my best!

Dooglus, I really enjoy this discussion! Cheers and thanks!

Otherwise the site would need to recalculate share for each investment with every single non-zero bet.

I don't think that's true. You would only need to recalculate the share for each investment tier, ie. 10 numbers.

I assumed that's what you were doing.

Thanks for digging through it! :-) It's all correct. Here is why:

If you invest 1 BTC with leverage 2, the site effecitvely lends you a virtual bitcoin, so that 1 BTC + 1 BTC = 2 BTC in the leveraged bankroll.

Suppose site profit grows and your investment has positive profit. Any profit. Let's say you earned 0.5 BTC on this investment. It's now worth 1.5 BTC, but in the leveraged bankroll it's 1.5 BTC + 1 BTC = 2.5 BTC.

As you can see the loaned amount does NOT grow with your investment. Otherwise the site would need to recalculate share for each investment with every single non-zero bet. That's the key to understand why leverage=n investment is not n * real_value in bankroll.

One of the downsides is that effective leverage, i.e. value_in_bankrol / real_value = (real_value + loaned_value) / real_value is not constant. It decreases when the investment profits.

For sake of completness the investments are described in FAQ. The math is simple, although at some point indeed you might wonder "why?".

TL;DR: loaned amount for the investment is fixed, so effective leverage does not equal the initial leverage.

What's going on with these numbers?



Look at the 2nd row. 2 times 15.275 isn't 30.275
Look at the last row. 10 times 10.638 isn't 103.338

It's hard to figure out how the math is done. The 7x row is weird: 0.01019145 times 7 != 0.07019145
It's like you're multiplying the first few significant figures, and leaving the rest not multiplied.

Good launch. I like that you have live stats for the site . Especially for the investments. Live stats and % of return is very good I love the transparency. So far it is 3% per month. Better then some I have seen and you still new. So I wonder if this would grow in the future.

The devs are not same. As far as I'm aware the devs of YOLODice are quite new on the gambling scene.

No, I am not Dooglus :-) Although I admin my very first adventure with dice games was with JustDice. It left an imprint in my mind.

And I am not ethan_nx. Smiley

I'd also like to state that I do not vouch for yolodice.

I expect I'll need to quote that in the future to defend myself against a QuickSeller attack. Smiley

Anyway, there are two new cool features added today: /rain and /tip. Quite self-explanatory I hope. This already made chat more lively!

Wait, Yolodice is not the same Devs as Just-Dice Right? Is just the concept is similar?

Browse through the site, Love this part : https://yolodice.com/#faq/investingv

Especially the leverage explanation part.

Just one thing there, with 178 Btc in bankroll, but no big deposit players.

Dev have any idea to attract more players? Smiley

Wow, I have registered with the site, hoping to get the best of it.

Yolodice this is a suggestion, you can introduce great incentive to attract investors and players to the site. My little suggestion

can this site beting use dice bot?

not yet bot supported lets say like seuntjie bot right.but there was available too automated bet and that cool I think
Yes, not yet. Since this site still new, and the lastest version of dicebot (V.3.3.0) didn't include YOLOdice https://bitcointalksearch.org/topic/m.17223406 but i think seunjti will adding this site in his dice bot in the future if admin wants that.
