I haven't tried any voting bots myself but from my brief research on them I think most people use https://steembottracker.com/#bid . From what I've gathered you pick a bot, send the bot your bid in Steem dollars and they'll come to your post and upvote it for more than what you've put in based on how many bids the bot recieved/how much you put in. I don't think many people have a problem with it, the main thing I see people having an issue with is when people upvote their own comments. I'm always interested in hearing about what other people are buying and their thoughts on different coins and strategies. Hope you do well on Tron and Cardano. Thanks for sharing!
