But you waste a lot of time for it. Is not better and profitable to click some sites and buttons in the internet?
Why would it waste time? A miner is something you configure and leave alone. It mines while you are sleeping ffs.
Doing paid-to-click websites is less profitable because it demands your full attention the whole time. You could have instead spent that time learning a useful skill. Something is seriously off with the way you think. I highly suggest you take time to stop and meditate.

Most likely the fan can wear out. How much is a replacement? $20-45?

The current market value now is higher than in the future. Every day that you keep it mining for 5 cents it might depreciate another 10 cents
