Trade perpetual contracts to earn Rh. Rh is calculated on a weekly basis, with each week counted as a period. There is no fixed $AST token allocation percentage for each weekly epoch within stage 1. This is termed 'blind mining' and each epoch's allocation will be determined at Aster's discretion. We calculate your share of Rh in each period, and then take the average of all periods to determine your final portion of the Rh airdrop pool.
