I'm familiar with this to be honest. Nothing I'm proud of being around 2011 I remember installing miners on some computers in the school I was attending then. Ultimately, I decided to delete them all before being caught and I have no idea where my wallet from that era is.

But lesson learnt is, if you're determined enough you can find an ethical way to mine and profit from cryptocurrencies. Whether it's Proof of Work or Proof of Brain like it is here on Steemit.

Thanks for the post @jrcornel
