Can you explain why bitcoin is not an illusion while you claim Litecoin, Dogecoin, Uno, QRK, PPC, drk, etc would be one?
What makes bitcoin no illusion which at the same time does make alts one?
Wouldn't this mean alts are in general without sense?
Do you think people would want to use bitcoin if there wasn't a choice to it?

I think your viewpoint needs an update.
If you were right you could expect crypto to not exist 3 years from now as there would be no sense in developement and an evolving process.
We could also abandon the word "cryptocurrency" as it would make no sense because in reality it is only "bitcoin".

You say "cryptocurrency" is a myth and only "bitcoin" exists?

Is ripple an illusion too? Nxt too? Maidsafe is also an illusion? And ethereum will also be an illusion as only bitcoin is 'real'?

Sounds like BS to me. And that claim stands there pretty detached from anything. Just a claim and nothing to back it up so far.
