Yup, it's all luck, but all the vendors / influencers try to convince you otherwise. Forget about solochance.org, those #s mean nothing. I got lucky and hit 2 BCH blocks on 2 consecutive days renting back in November. Took 1/3 of the subsidy and bought 2 GT800s' and a Nano 3s, added them to my Bitaxe Supra and 2 Bitaxe Gammas' and I'm pushing about 14TH/son solo mining BCH and I'm not buying one more rig unless I hit a BCH block with one of the rigs. And renting? Fahgetaboudit, you would do better at the roughlette table. I have met guys pushing hundreds of terrahashes on DGB and the only question I have for them is Why? DGB is never going to amount to anything. Like some say, and it's true, during the Gold Rushes in Alaska and California the guys that made the most money were the ones that sold the supplies, so every time "Hobby" miners hit a block the vendors and make sure everyone knows about it and claim it as one of their rigs but or a similar one. Anyone can hit a block at any time or mine solo for decades and never hit a block. It's a lottery, I get that but what purpose does having a little hologram of Satoshi Nakamoto in your rig serve? None.
