Last week I was cleaning my bookmarks and just opened all of the "Mining" folder just to check if any of old players was still kicking. I left the scene in 2014, after the MtGox problem and apparently I had almost 0,05 BTC just chilling in bitminter pool! Sure, the 0,33 that I transfered from that pool to MtGox in late 2013 worth almost 15k€ were just vanished, but not is lost after all! Check your old pools, great advise! ;-)
