That comment signals @tipu to send you 3 STEEM from my deposit.

Also, it's your choice. Do you want the 3 STEEM tip or the 20 STEEM bounty prize? (read first comment from steem-bounty).

I understand it is over, but I´m only confused because when I made my comment there was only 19 comments in the post (which means that those 50 had not been claimed at that moment).

Answering directly to your question, I would prefer 3 STEEM!
