Bitcoin is not perfect and so is every other innovation man has created.
Not perfect in the sense that it has pros and it also has cons.
-snip-
Not perfect because they don't have to control Bitcoin like they do in fiat currencies.
Bitcoin will not be perfect for them forever as long as Bitcoin is still present in all transaction activities. They don't want to acknowledge Bitcoin by saying various negative things, for me it doesn't matter because Bitcoin continues to be active either as currency in every transaction or as an investment asset.
The stronger they create FUD on Bitcoin, the more Bitcoin continues to gain trust.
