Hi maochitse,
good you ask this question, let me clarify:

When you buy a contract and use the whales promo code, the whale receives a small fraction of hashpower.

Let's assume you buy a x11 mining contract for 2 years for 100 Mh/s - in this case the whale would also receive 3 Mh/s from your purchase because you used the promo code. In this case you would receive upvotes for 2 years until the contract runs out.

It sounds a little bit complicated - guess i'll create another post tomorrow to explain the whole process in detail.

If you have any more question, i would love to answer them for you!
