Probably very little. Most people only want it because they think it'll go up in value, and the only way that happens is if more new buyers increase demand.
That's the similarity with the Ponzi. When new buyers 'run out' the value drops as there's nothing to sustain it, which I think we're seeing now.
Like I said, I'm not shitting on it. Bitcoin will have an upward trend again.
