that crypto currencies are really just starting and there is a very high ceiling Starting at what? What is the value proposition that is actually in play here, for which there is some hard evidence of it's existence, other than a speculative frenzy? It's a bit galling how many people this go 'round are just outright saying "yeah, it's a ponzi, come on guys hop on! there's a high ceiling! hope you get your chair when…
If you think that some future economy will run on cryptocurrency (not totally far fetched IMO) and that currency will have network effects (I don't really see this yet, apart from deflation via speculation, which will stop eventually, it's not stable) then there's a possibility of a winner takes all outcome. But it's very easy to doubt any specific currency will be the final winner.
But here's the problem with this idea as being some buoy for bitcoin/cryptocurrencies, once an economy of this sort develops with some semblance of structure, that market is going to seek out inefficiencies. First on the chopping block? A massively inefficient distributed currency system.
For this reason I think any sustainable use case of a bitcoin like system is necessarily rather niche, and rather 'seedy' or worse, ransomware, etc. But if all the bitcoin dreamers fade away, it becomes much easier to counteract the use of btc-like systems for ransomware extortions and the like.
