This is the generic Manek.io wager contract where all Mankek.io bets live unless
otherwise stated. With a standard end timer. Betting can only be stared by the
admin. Who sets an endtime and number of picks. Betting can only be ended once
the timer is over or betting is ended and a refund is triggered. Players must
withdraw their funds once betting is over. There is a single jackpot winner which is
based off the hash of the block 200 before betting ends and will be valid for 6000
blocks (about 1 day). The jackpot winner must claim their prize or it will
go to the next winner.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
BedID's [bID] reference a specific bet, bet names can be looked up via the viewPck
method.
