Today I was clearing out old ASICs from storage - Antminer S9s, Whatsminer M3s. Dust, noise, memories. These rigs no longer turn a profit even at our $0.03/kWh rate, but I just can't bring myself to trash them.
Why We Keep 'Dead' Hash Rate
1. Nostalgia. My first mining rig, my first satoshis.
2. "What if" - Bitcoin rockets to $100K and they become viable again.
3. Parts inventory - fans and power supplies still have life left.
My garage neighbor uses an S9 as a workshop heater - funny, but more efficient than an oil radiator.Currently calculating ROI for new ASICs post-halving - the numbers don't look good. Maybe it's time to pivot? How do you decide when hardware is truly obsolete?
