Dude, thank you for posting that map--the information contained therein was not something I was familiar with, and I honestly didn't think there were that many countries that had outlawed bitcoin or restricted it.  Very, very interesting and I thought Russia had banned bitcoin for some reason.

OP, I got questioned by my bank once about a bunch of small bitcoin buys that I did through my checking account.  That was back when bitcoin was in the $400 range and Circle allowed you to buy small amounts.  I was asked by the bank branch manager what they were all about, so I told them I was buying bitcoin.  Nothing ever came of it since I did nothing wrong.

Banks can be pains in the ass sometimes, but they have their business to look out for and what their customers are using them for is definitely their concern.  My bank didn't know I was buying bitcoin.  It was just a weird (maybe suspicious to their eyes) bunch of small transactions that caught their attention. 

Then I wouldn't sweat it.
