I just read about a tipbot on REDDIT to tip an account with IOTAs. IOTA is the perfect currency to do the job because there is no fee.
You just have to make a deposit to the tip bot to begin. You can choose to tip a specific amount of IOTA or MIOTA if you want to send bigger tip to someone!
I'd loved to see that coming on steemit and facebook.
You can find information about the bot here : https://www.reddit.com/r/iotaTipBot/
