Is it sense ti buy it? How much bitcoins i can max get from this?
thanks for reading!
No don't spend 25 dolars on one of the old block erupters. You will lose money it is only for fun. And on laptop mining.... don't do it pushing your laptop is a bad idea its not meant for 24x7 high intensity mining. Not to mention your using more electricity then you make on laptop.
If you want a stick miner to learn get a compac they are still going to be a loss as far as ROI goes. But it is a much more current lotto miner. Also might look at getting RPI so your mining on low cost.
But again all stick miners are at a loss... so its really just learning you will be doing. Not making money.
