I am really happy and surprised to see that how many prediction months we have successfully passed on @Bitcasino and with increased participation so appreciate Karl and whole team for it and organising it each month.
Agreed. These prediction contests are easily some of the best contests in this forum primarily because they are free to enter and skill does help to some extent along with luck while predicting BTC's price.
Its popularity has encouraged other sites like Sinbad to run similar contests using similar rules.
