But hopefully, not like the euro, bitcoin is an investment! not cash, not pocket money!
It is a Privilege, as in the privilege of securing your wealth from the banksters and bypass them!
...
If you take away merchant acceptance and all the practical usage, that means you can only use/trade your 'investment' on centralised BTC/fiat exchanges, subjected to AML/KYC regulations and completely opened to the same (if not higher) risk as your fiat holdings.
And what would give your 'investment' the value if you slaughter huge % of demand and make BTC completely unattractive for any new people to join?
first there is no proof or data regarding that alleged "huge %" of demand. its a smoke screen.
what should make bitcoin attractive to new "users" (i'd rather refer to them as "investors") is that they would see in it kind of a parallel way (if not the only way!) of securing their wealth, bypassing the banksters' bails-in and their sand castle of degenerated financial vehicles. (or even avoid/reducing taxation for that matter.

)
why do you think people around here were all exited because of the greek crisis?
with all respect and compassion for them greek peopel, i dont think because of some average screwed greek could buy some bread pitas with bitcoin.
sadly enough most of them are left with nothing anyway.
hence, the only way bitcoin could reach new ATHs, in my view, is because of relatively "rich" people
injecting actual money in it, because they would consider it a
privilege, a decentralized-anthropo-resilient-cryptographically-secured-safe-haven.. it is purely mechanical and is so not because of the "regular dude" wanting to buy some pizza or some usb chip on the internet.
edit: plus, just look at how horrible it is to buy your first bitcoin? its so much worst than to enter your credit card numbers! and all the "atms" in the world wont change anything.
