CoinUp.cc - new online lottery project

[CoinUp.cc]

Hello! We would like to introduce you the CoinUp project.
Coinup.cc - is the online lottery project, with BTC as the currency. On our website you can play the game both for the real and the virtual currency. The system is totally pure. You can read more about the game principle in 'Fair game' section.

A brief description of the game: the system picks up a random number and encrypts it using the md5 algorithm. After that, the players bet forming a 'bank' with N BTC ammount. Then the number N is multiplied by the number that was encrypted, and that is how we get our lottery ticket. If you have it, you are a winner, you take it all.

I am one of the co-founders of this project. You are free to ask questions, offer us your additions. Let us know about the system errors and get a reward.

Good initiative. However, a lot of games like dices, and other probably fair. There is a lack of casual games for android, ios etc

[CoinUp.cc]

Also, the project have mobile version of site.
So you can play anywhere using your smartphone.

Nice website desing the problem is that nobody plays with real bitcoin. I think you game is similar in some ways to the cs:go gambling communities like https://csgojackpot.com/

Also the rake is 6% for the casino, from $100 they take $6, I think it is too much for a website that is just starting, for example primedice pvp offer 0% house edge.

Really great platform and nice design but I would recommend you to use a different domain. A .cc domain doesn't seem trustworthy, I would recommend you to get a SSL certificates in order to secure the platform more.

[CoinUp.cc]

Thanks to all for answers and recommendations.
We decide, that our service fee will be lower, than now. From 6 to 5.
One interesting fact, that we aren't a casino or like that. We are create a project, which use fair play system without "underwater rocks". Also, primedice project have 0% fees, because it's like a casino... we all know, that casino forever wins.
In the near future, we will add SSL certificate to site.
In conclusion I'd like to say that we will advertise our project in different forums, so in the nearest time many people will play in real btc.

[CoinUp.cc]

We are modified our project.
The list of modification:
1. Add SSL protocol on site.
2. The projects fee was lowered from 6 to 5%. 1 percent goes to referral system, others percentages goes to blockchains fees.

I haven't seen any successful lottery projects here on the forum. I'm skeptical but luck to you, maybe you'll manage to make it popular

I think your chat has a little bug... when i write a msg or someone write a msg it don't auto refresh here

Yeah, I know. Actually, it's not a bug. If you send a message, you should just scroll down and you can see your message)
But, in nearest time we will change the chats algorithm for more comfortable communication.

NIce idea ..... there are not many bitcoin lottery sites....if they exist,they have very poor UI so basically if you guys improve your UI you can attract newbies as well as others also....I will give your site a try..

You need to change your provably fair system - at the moment it's too easy to cheat. It's very easy to find the MD5 by brute force because you're only using a 10 digit number and no other protection - my computer's not super-powerful or anything, and can crack it in a second. The usual method is just to add a long string of random characters to the value to be hashed.

However, the provably fair system also has another problem for this kind of game - since the actual number is pre-generated, while it's provably fair between players, it would be easy for you to make a fake account and win games on your own site, and would be undetectable by players if you were subtle enough about it. I think the usual solution for this is to have a step in your provably fair system which relies on some kind of random data that you can't control - for example, the hash of a future bitcoin block, though that would require your games to be delayed until the next block is available.

Today one of our users tell us about it and now we paid him small compensation.
After that we change the count of digits. Now it's 20 digit numbers.
About fair play - we will be honest with our users and won't create fakes account. We have good fees from every game (about 4-5%). About blocks... it's good idea. We will add 2-3 others sorts of game in the nearest time. And one of them will be this sort of game, which you offered.

Yeah, that user was me. (Edit: the compensation was received, thanks!)

Personally I would secure it further - sha-256 or sha-512 instead of md5, and characters as part of the string instead of just digits - but it's good to see action being taken quickly to improve things. Good luck with the site!

Sorry for misunderstanding. My partner didn't received my message at first time. I told him message about you again and he send you our small compensation. Thanks for helping.
