It's a nice list, but I disagree with:
#3 (Bitcoin is a currency) -- The reasons are confused. They say that Bitcoin is a payment system, therefore it is not a currency, but the reality is that Bitcoin is payment system with its own currency. Maybe the author misunderstands. Anyway, I don't see why it wouldn't be a currency except when there are some arbitrary requirements, such as it has to be state-supported.
#9 (It's a Ponzi scheme) -- I don't disagree that this is a myth, but the argument is poor. Bitcoin can't be a Ponzi scheme because it is 100% transparent and there is no operator. I think that many people use "Ponzi scheme" when they mean "pyramid scheme" because they don't know the difference. Bitcoin is not a pyramid scheme either.
#5 (Chinese citizens can't buy bitcoins) -- I don't know anyone that thinks this or even cares.
#3 Agree with you but I don't agree with the fact that it's "low-cost replacement for credit cards and other payment mechanisms.", miners + electricity per transaction is expensive
#5 Didn't the ban came after the huge pump? I think the author missed something..
#9 Agree with you, there is no central operator hence it's not a Ponzi (Services, like exchanges, could be)
Also:
#6 bitcoin is a store of value, the blockchain is there to support the value
#8 I am happy to give my personal details to a bank, why should I keep my public address a secret if required by the law?
