there is no bad marketing. blockchain technology kinda need these idiots too to "spread the word" and unfortunitly bitcoin is full of people who doesnt understand how it works.
I strongly disagree. Bad marketing can do a lot of harm by damaging a building trust relationship. Claiming things that are not possible is one of the worst techniques, because it soon leads to disappointment. Disappointed people are the hardest to win back for an idea.
Bitcoin does not need marketing through media campaigns or by spreading half-truths and making false promises. Bitcoin's best marketing is just like its network: p2p.
Bitcoin's killer app is not some fancy blockchain n.th layer technology. These are added bonus. The real killer app is free worldwide p2p payments with a secure and sound currency via a decentralized network. Almost everyone that experiences Bitcoin in action is hooked by it.
ya.ya.yo!
