It really is isn't it? The market just hurts everyone involved besides retailers - as others have said it's far too risky to substantially increase production like AMD did a few years ago and had to write-down stock. People don't seem to understand that the turnaround time from order to product for processors is measured in months - being able to accurately predict a staggeringly volatile market that far in advance is near-impossible.
It's not great business for the fabs for the same reason - they have a finite capacity they need to fill and if/when the market collapses again, they're out of pocked. Fabs cost on the order of billions and take several years to build, so 'just make more' is not that simple. And I doubt even doubling production would make a jot of difference at the moment.
I don't know what the environmental impact the fabrication causes, but the electricity demands are pretty catastrophic. And it's pretty painful to see so many carefully-engineered products dumped into a task which is entirely pointless by design. I just see the whole thing as horrid now. I can understand the argument for it being a good concept, but it's badly flawed in the real world when greed etc come into play.
It's really not decentralised in reality, it's not remotely anonymous, it's far too volatile, transaction fees are laughably high, there's no financial protection e.g. chargebacks, the processing time is stupidly high, and it's grotesquely power-hungry - something like 215kWh for ONE transaction for BTC! So... what's the attraction of using it as an actual currency again?
