what about electricity costs of running a Bitcoin node? which hardware you use?
Discussion
For me it didn't make a difference. Running an i5 9600k and a mini pc. What made a difference in the electricity bill was the shower and the air conditioner
Agree. My node runs on a Raspberry Pi, but I have a 3 year old laptop (i7-8650U CPU @ 1.90GHz) that acts as my server that runs everything else, including my relay.
My Raspberry Pi uses a few dollars a year of electricity. You won't notice it.
