I would add to this poor bitcoin privacy.
Bitcoin core dev, Greg Maxwell, says that many companies are scared of bitcoin, because if they used it, all their transactions would be made public.

True. Lots of people talk about the anonymous part of bitcoin, but that's fucking wrong. Once the adress you used is known, every transaction can be followed. There is no bank secret in that!
I am pretty sure that this can be overcome by using a middle man solution like BitPay or maybe some bank will start doing that for some fee. I could also think about an adress mixer but that might not be legal...Furthermore, I think the big ununity in the crypto world itself is not the best publicity to the outside and think also about the scams the alt coiners produce - also some deep bitcoiners are getting confused sometimes about alts and loose their FIAT or even BTC there , but should know better....
Whole point of bitcoin is not to use any third party or middle man. For two reasons, imo. First, with fiat you already have middle man for transactions, which are banks. Hole point of bitcoin is to avoid it. Second, blacklist. A thid party can control/censor your transactions, and again point of bitcoin is to avoid it.
And speaking of BitPay. BitPay is not a very good example in this case. They are already censoring and blacklisting transactions:

Blacklists are inherently evil, they seed control to the author of the blacklist and that control is absolute. This is one of the fundamentals problems we have in our banking system today.
