I don't know if this fits the Altcoin category, but it should count as a decentralized currency.
Gratitude is the best currency you can give to other people or exchange for anything. Even just a simple Thank You can make you feel good and make others feel great.
Imagine if that were a currency, decentralized yet offline? I've come up with a solution for that.
All you have to do is take a small piece of paper, and write "Thank You" on it, and give it to other people in exchange for what you want, as a written way to say thank you.
Reading your title before I open your thread,I thought I will stumble a coin that is very much different from what we have here,but I see no innovation just an idea,this should be in the altcoin discussions,not here because your ideal coin is not yet live.
