Thanks, Josh Bitsolo admin. In one week, a lottery might cost you 2 (for one ticket) and give you a 1 in 175 million chance to win 100 million (ignoring smaller prizes, splitting prizes, etc.; complicates things too much). You can unsubscribe with one click. This gives it a return on investment (ROI) of about 29, so we'll treat this as our baseline: if it's lower than this, it's worse than the lottery and you shouldn't "play". As long as you're in good communication with the network and have a hashrate measured in something better than minutes per hash, yes, you technically do have a chance of successfully mining a block, even if your hashrate is tiny compared to the whole network. Not counting the upfront investment, this is a 1,361 ROI, so it's worth. I will be bringing a new mining server online towards the end of this year that will use much more advanced software for the site interface and support a much wider range of protocols/coins.
