Just don't panic.

According to our estimation, the size of the
underground economy in Bangladesh was only 7% of nominal GDP in 1973.
Since then it
increased phenomenally and in 2010 it stood at 62.75% of GDP
And if it raised in the same amount since 2010 then the illegal economy in 2014 must be around 90% in Bangladesh.
Now look the story from the other side.
That the government of Bangladesh has nothing against Bitcoin it proves only that they are considering it more legitimate that 90% of the other parts of their economy.
