this is something different from traditional betting..... instead of betting on the outcome of sporting events and dealing with odds, you're instead choosing and playing for an entire season of the sport

Hmm...an "accidental fork" happens when two or more miners find a block almost simultaneously.

These blocks are then classified as ‘orphaned blocks’.

There is bankroll management. It is relatively straightforward. First, you'll need to set a budget for how much you’re prepared to spend on your betting and then never exceed this limit.
