Found a pic of my old mining setup (12mh/s scrypt mining 3.6kw - Litecoin, Dogecoin, etc....) Originally setup in early 2013 (too late to be mega rich, sadly), but still have some of the coins. I joined forces with some friends and we went at it hard with a total hash power of 110mh/s (a puny number by today's standards). Didn't take long to realise the diminishing returns were going to eat us alive so when the leccy bill got too high at home, i moved into the unit you see on the pic. In that unit i had free electricity, well, until the landlord got the first bill....lolz. A few months later i got a bill that was too big to swallow so the mine had to go.
The greatest thing to happen at that time was selling the altcoins on ebay. People munched them up faster than we could get them to the exchanges. It was glorious. After some time, paypal decided to shut altcoin sellers down because they were selling non physical goods and people started to figure out they could easily scam altcoins from legitimate sellers by opening a dispute in paypal saying they did not get the coins they paid for. (happened to me several times).
Got bored of the whole 'pump and dump' manipulation by serious altcoin traders on the exchanges after that so just lost interest, until recently when i realised that not only had Bitcoin gone up in value, but i had some free coins from the 'hard forks' which resulted in Bitcoin Cash, and Bitcoin Gold.
So, trying to get my head around the mining thing right now, as times have moved on, but i'm pretty sure its going to be at 'hobby' level for me if i decided to build another setup.
P.S: Why don't i liquidate the coins and buy a pin with fiat? - Its quicker and cheaper to pay with Bitcoin and there's no huge amount of money showing up on a statement the missus reads.
