Same. Although with the curse of hindsight, I painfully recall choosing to run SETI@home instead of "mining" some weird digital currency called Bitcoin back in 2010. So, painful.
Exactly the same here. Ran SETI@home on all my machines back in the day. I remember running this weird bitcoin ‘thing’ for an entire week on my main machine which generated around 1.4 btc. Then I DELETED it.
