In terms of output, it's possible to take the same risk as mining, but in terms of the processes involved, it's definitely not the same. Betting means you give up what you have to breed, while mining means you have all the tools you need from the general to the most specific. It's simply like this: Farmer as a subject where he does heavy work that will produce something from what he does (miners). Then the results he gets (objects/tokens) can be bet or he keeps. The output remains the same but the process is very different.
