I do not agree with you. You can always exchange bitcoins for currency. Bitcoin was invented in order to demolish the existing monopolized banking system and return the power of the public. What bitcoin does.
It's correct. Easily transitioning from cash to Bitcoin without the government's management is a loophole for offenders to easily launder money. This is also one of the main causes for the governments of some countries to issue bans on Bitcoin. They cite many reasons for banning Bitcoin. Actually, the government can not manage the value and transactions related to Bitcoin.
