I don't know I just started on trying to gather a little bit of ETH, so far only 0.022, just over $50.00 according to Ionomy, but I figure 25% of what I get on Hive-engine, it would eventually grow, slow but still grow.

I am pretty pleased that I am doing pretty good on my curation earnings. I try to get 12 hours of votes out when I get up in the morning having coffee cruising my feed. Then before bed I shoot for being voted util noon the next day.

I follow a good group of people that post on a pretty regular basis, it also helps I like their content.
