Square just showed up to a conference with a modular $BTC miner that you can actually repair yourself.

No more throwing away entire rigs when one component dies. Jack Dorsey's team is pushing for mining hardware that doesn't turn into e-waste the second something breaks.

This is what decentralization should look like at the hardware level. Less vendor lock-in, more sovereignty for miners.

If this scales, it could shift the economics for small-scale miners who've been getting squeezed by rising difficulty and zero repair options.
