Your hall
Cards fill racks. Racks fill rooms. Both run out, and the power feed runs out before either. Everything you burn to get past those limits is $GPU that never comes back.

Burned to upgradeReferrals
10% of what they mineAnyone who starts from your link earns you 10% of everything they mine, for as long as they mine it. It costs them nothing — their rewards are untouched.
The 10% is paid from a dedicated 20.00M slice of the fixed supply — not minted on top, and not deducted from your referee.
Next halving
5 nm → 4 nmElectricity halves with the reward, so margins survive the cliff. No countdown — the halving lands when supply crosses the line.
What $GPU buys
Cooler
99k$GPU−20% watts for every card in the rack, permanently
Takes a rack bay of its own. Buys headroom in the limit that actually blocks you.
Overclock
69k$GPU+25% compute for 7 days
Burns life faster than it adds output. A bet on the current epoch, not an upgrade.
Warranty
0.045BNBRestores a worn card to full life
Paid in BNB, so it lifts the floor instead of burning supply. Adds no watts.
