I'm not a pessimist by nature and always champion the little guy when I can, but every year more miners are being made so every year things change. I don't doubt you will find another block, but it seems like it could be like this more and more.
I point out the share levels every once in a while in the discord channel, best so far this month is a 3.9T share.
Less than 5 times higher than that equals a block.
We've also had 5 over 1T so far this month, it's just random, we'll get the next one soon enough.
