I've had a $60 and $80 up-vote to a comment
I've never experienced that particular joy, but I have had several cases of spur-of-the-moment comments earning more than posts that I've spent hours on. This kind of random intermittent reinforcement is more addictive than meth.
Maybe!
I use steem.supply to check post payouts/comments and the comments are always ahead. Clearly those numbers are one-offs for me, but i do see plenty around splashed upon other lucky Steemians.
Have a 100% er on me!
