ORE

Mine blocks. Trade hashpower. Earn rewards.

Summary

ORE is a cryptocurrency mining and trading game. Miners compete to earn block rewards by buying and selling hashpower in an open market. The more hashpower a miner acquires, the greater their chances of finding the best hash and winning the block reward. Will you play it safe or hit the motherlode?

Step-by-step:

1. Buy hashpower.
2. Sell to lock in profits or losses.
3. Hold until the end of the block to take a chance at striking gold.
