Etherium sounds like a great idea, and a great approach.  But I&#x27;m afraid it&#x27;s going to end up like GPG: Technically awesome, strong, capable, and useful - but completely out of reach of most of the people you&#x27;d want to use it with.<p>Every time I read a &quot;Getting started with Ethereum&quot; guide which involves 7 steps just to buy Bitcoin (from a site nobody&#x27;s heard of) and then set up a wallet, I watch the number of potential users dropping like a rock.<p>I hope very much that it succeeds enough to justify its learning curve, as it&#x27;s an interesting idea.  But I suspect that outside of a few <i>very</i> small markets where it offers the ability to do something completely impossible with any other method, having an ethereum interface for your product or service will be roughly equivalent to GPG signing all your emails: People in the know weren&#x27;t that concerned anyways, and nobody else knows enough to care.
