I do that because it triggers tipping bots that give hive-engine tokens to the person I comment on. Usually you have to have a certain amount of the token staked in order to be able to call the tipping bot. I like hive-engine tokens and have a lot of many of them. To me, they are just for fun and I have no expectation of any profit from any of them. Not Financial Advice! :)
