76 votes during 7 days, but NOT even one single vote on a comment, not a single vote with less than 100% power.

That's just sad. For leofinance to succeed, people need to know that it's OK to upvote comments here. There's no convergent linear penalty like there is on Steem or HIve. It's OK if a post or comment has zero prior upvotes, the curation is still the same regardless.
