partially wrong, so they are partially correct. Right? On "secure" consider that Bitcoins are not secure in themselves, the algorithm to verify them is. You can still lose Bitcoins, or they can be stolen. The user must take steps to make them secure, and this also applies to anonymity. I believe this is what they mean.
Some of the points raised suggest more than a passing interest, with more thought than many I see in the community. How many are considering the consequences of a few more generations of ASIC miners - like centralised mining and blockchain nodes?
Well I was waiting for someone to make the completely incorrect. It depends on how you view it.
If not used correctly, nothing is safe right? Cash, banks, internet, anything pretty much? Correct?
Well that is a possibility, we can't know what is exactly going to happen by then.
