Re: [Guide] Solo mine testnet bitcoins with bfgminer, Bitcoin Core, and a CPU/GPU
It somewhat surprises me that more people did not spin up a rig just for fun, but on the other hand the coin was worthless and energy & hardware did cost something.
Don't remind me 
I should have done that when I first read about Bitcoin, which was years before I joined Bitcointalk.Quote
@LoyceV, after browsing a bit online, it seems like there are modern CPUs now that can compete with something like ETFBitcoin's 100MH/s GPU.
It's just that your CPU is old.. old old..
It's old indeed, but works very well for it's task: pushing bytes to the outside world.It's just that your CPU is old.. old old..
This Xeon CPU is already faster in finding Bitcoin vanity addresses than my (old) laptop's GPU.

From 2011 to 2023, well, things changed. An i9-9900K from Q4 2018 even manages over 100MH/s, it seems like. [4]
Buying a CPU just for hashing is a waste of money (and electricity). That's 95W that could be used for better things.
