Hi,

As a potential investor, I am very concerned by what I have seen looking at your lottery algorithm. There are 2 glaring issues that undermine the legitimacy of your lottery and are astounding given the millions that will soon be raffled on the site.

1) Any customer who has purchased a ticket using number 49 has been cheated. Your algorithm uses modulo 49 which makes it so only numbers 1 through 48 are drawn.
2) Your algorithm discards repeated numbers and moves to the next 4 character section in the hash. This is inherently ok, but there are no safeguards to prevent a bitcoin block hash that generates duplicate powerball numbers exceeding the unique hash length. This may not happen for a long time, if ever, but there are already 18 prefix 0s on the bitcoin block hash, reducing your available seeds for the drawings, and this will only decrease in time. When it does hit, your algo will crash. For a lottery based business understanding the impact of ' small odds', this should go without saying..

https://github.com/TrueFlip/prizecounter/blob/master/algorithm.py

edit: 4 character, not 4 bit
edit2: this also applies to the golden ball with modulo 26

I am a little bit worried about the big error in algorithm, the equal distribution should be one of the most important elements in a lottery.

Second thing are the names and pictures on your team description site:
https://ico.trueflip.io/newico
Some pictures of the members have different names and are doubled.

Can you comment this please.

Looks like you have similar rules for tweets of SONM but this would create a spam like thread and I would suggest to open another thread for bounty and to keep things posted there

Hello alinda

Thank you for your suggest!
I've taken it.

Just made new account there but not option to make deposit with other altcoins instead of BTC. Maybe my account have some problems to make deposit using LTC.

It seems I couldn't understand you correctly. You can't buy tickets for alcoins now. Such an opportunity will be available only after the ICO starts. But you will be able to buy tokens for altcoins from June 28.

Best regards,
Trueflip.io

Thanks for this reply I was actually asking how to play lottery with altcoins so that I will wait for June 28 when this will be up for place bets there.

Hi, I joined the signature campaign, why is not it appearing on the spreadsheet? Will the stakes count for a week from the day I joined or is there a specific check-in day? Is avatar and personal text required? Thanks.

Hello Karodozo

1. Now you are there in spreadsheet.
2. Stakes counted from the day you've joined.
3. Avatar and personal text give you +0.5 stake per week. They are not required.

Welcome!

Weird, I'll wait for a response, maybe they are using an updated version of this algo or maybe it's just an early version.

It says it was updated 10 days ago..Also, anybody can use the 'Check the transparency' feature on their website and enter a custom hash with a character 0x031 (49 in decimal), it does not result in the digit 49 being drawn. All of this is very surprising given the professionalism and software skill that went into the website.. but the money making algo looks to be an afterthought. Embarrassed

Yeah I see it too. are you sure 49 is supposed to be a possible number to be drawn? Join the telegram and ask to speak with the developers, if it's really an issue they might give you a bounty.
