Will PM help you then? I doubt it. Mark Dice has given people on the street the choice between a candy and a silver bar. All of them choose chocolate.
Who is actually taking blockchain as payment?
The blockchain is the ledger and not used for paying. You can pay with bitcoin at any place which accepts a normal credit/debit card. I have a Bitwala bitcoin debit card. I am feeding it with bitcoin and I am able to pay with fiat at any place accepting a Visa card.
I just don't see the liquidity, ease of conversion that something like gold coins has.
Try to divide a gold coin. A bitcoin can be split into a million pieces.
The growing Bitcoin competition is another problem.
Why? Freedom comes with competition. No nanny to protect you, yes. It's a wild west out there.
The barrier to entry argument is not holding up.
Anybody can create a "fork", a duplication of an existing crypto currency. But such a fork does not have the infrastructure support of the "real thing". For a fork there are no developers, no miners, no community.
All that said: I don't want to hype BTC. For instance, one disadvantage (for a non-trader) is the volatility. A long-term holder needs to stomach regular 10-30% swings.
