Total noob here. Didn't even know about ethereum until today. It sounds like a great concept. So I joined the forum.
I have an idea for a currency that distributes a dividend to all users. You will have to pay for the dividend with every transaction. I think 1% sounds fair. I wouldn't call it a transaction tax, I'd call it a deposit. This would be an investment in the currency and incentivize adoption and reward stimulation.
I've never used a cryptocurrency before and the technical jargon usually goes over my head. So I hope you don't mind really dumb questions, because I don't know blockchain from a hole in the ground.
