If power consumption isn't an issue, is it worth my time to power up an old laptop and have it CPU mining? It's only like 5 years old so it's not a great CPU.
The laptop is pretty much dead to me anyway so I don't mind if it's quickly killed by the process.
if you have free electricity and free or hardware that you use in other places or old hardware then you can always befit. that being said you will not have a very efficient rig and wont get much money but if you don't care then have fun.
