    Sports betting between friends▲21

    With my friends we wanted to have a nice friendly competition (no money involved) about the football worldcup by predicting the results. I though this might interest other groups of friends so I coded a website just for that in 3 days. Nothing ground breaking but I like the suscription system "Doodle" style with just links, no personal infos... Tell me what you think !

    Ethercup: Place Ether on your fav teams of the FIFA Worldcup 2018▲5

    Hi guys, I am building Ethercup and I wanted to show you how it works: https://ethercup.github.io/ . On the website is a demo bet live right now on the Kovan test network. This bet opens today and will close in a few days. A How-to is provided on the website, but you can check out the code directly on GitHub: https://github.com/ethercup/ethercup.github.io There's no bug-bounty program, but I'm willing to share profits (if it'll yield any) in case you can break it and point me to it. Looking forward to hearing your feedback :) Also, feel free to ask…
