not very good odds on your thinkpad.. but if you set up a handful (3-5) of high end ASIC miners and mine BCH (10x more difficulty/hashrate on BTC right now) without a pool for a year, there is a realistic chance you'll get lucky and mine a block (worth about $17k). The numbers are changing all the time, but when I last did that calculation I was surprised.
