Where does crypto fit in to the AI industry's est. $7.6T buildout? Once fit can be found in decentralized GPU networks. NVIDIA's older chips (A100s and H100s) still rent at prices that suggest 5-6+ year useful lives. Frontier AI labs constantly upgrade to the newest hardware, but the older chips don't get thrown out. They get repurposed for lighter work like inference, instead of training. That's where DePIN comes in. Networks like Render and Akash plug older GPU capacity into a global rental market. Bittensor takes it further with subnets that run decentralized AI services on top. Translation: as frontier labs rotate to new chips, decentralized networks become the natural home for those second-life GPUs.
