In 2009 I started mining #Bitcoin with a brand new Radeon HD4870. I barely knew what Bitcoin actually was and had absolutely no idea what it would become. I was just a teenager gamer with a high-end GPU, trying to make good use of it in spare time.
Then after a few months I questioned myself: am I getting something out of this or just wasting electricity? I made the math and realized "it was not profitable", the cost of mining was higher than the value of Bitcoin I was receiving. So I decided to stop mining to save my Dad a few bucks of electricity by the end of the month.
I mined total around 0.6 BTC, which at that time was maybe less than 100 USD. Also lost that wallet that is now worth thousands because I stored the keys in an inactive email. Had I kept on mining despite being not profitable, I would be a crypto millionaire today.
I learned my lesson. That's why I keep mining Monero even though on paper it is not profitable.
