Is Our Hardware Supply Chain a Weak Link for Bitcoin?

People often forget Bitcoin is a tech protocol, not just a price tag. We're super focused on J/TH, but the hardware supply chain is a massive weak spot. If a key foundry goes down, we’re in serious trouble. Are we really overlooking the hardware resilience risk?

Not really missing anything, just thinking too much. Only two foundries, TSMC and Samsung, make mining chips. If one fails, it affects way more than just us miners, like smartphones and GPUs. They dominate the market for cutting-edge chips, so it’s a global issue, not just ours.

If TSMC or Samsung has issues, we shouldn't even worry about mining ASICs. The real disaster is losing power for smartphones, GPUs, and network devices. That’s the big picture.

Even in a supply crisis, both miners and attackers suffer from rising costs. Mining becomes pricier since new hardware isn't just sitting around, pushing used ASIC prices up. So, maybe the hashrate won’t tank but could dip a bit if nothing else crazy happens.

Interesting take. Makes me think about how the market self-regulates. Is that what ultimately protects Bitcoin from supply shocks?

I stick to hardware wallets with open-source code and schematics. This way, anyone can build a DIY wallet globally, minimizing risks. SeedSigner is a great example, and you can pair it with Satochip cards.

I wouldn’t say there’s 'inherent' market stability. But Bitcoin has safeguards like the difficulty adjustment. If hashrate drops due to hardware issues, it’ll stabilize in a few weeks as mining gets cheaper. Plus, mining’s moved to profit-focused firms, not just hobbyists, so rapid declines are less likely.

Good analysis! I wonder if a massive sell-off could lead to centralization, shifting the attack focus to collusion instead of just hardware costs.

I doubt that. Big mining companies rely on heavy financing, mostly from going public. If they crash, it’s unlikely new firms will raise that kind of capital. We might see a shift back to smaller operations instead.

Your point about the risk of collusion after a capitulation is solid. Strong arguments!
