well, there is a bit of luck involved with finding a winning hash for a block. your "luck" just increases proportionally with your effort
Discussion
Not luck in my opinion. Statistical. The amount of work put in is a percentage of the hash. Percentage of hash = percentage of blocks found. Just my rudimentary understanding. Very happy to be wrong and learn something.
I agree with you. I think ultimately it comes down to how you view or define luck.
