Maybe we should just get the clarification just once and for all, the ban we are talking about is of two types, the one that the government place on the banks from using bitcoin and the one the government enact as law against the people from using bitcoin for any acceptable means of payment, so there could be ba as well as bitcoin being an acceptable means of payment which indicates banks were banned but it's legal to use bitcoin in most applicable countries.
Most ban mean,the government will make a law to reduce the usage among the people.This is mostly done by the small countries to reduce the money flow to the external assets.Since crypto currency was the digital asset,the amount of holding can’t be find by the government,for this reason government ban or legalise the cryptocurrency.Legalise will help the government also to get some taxes from the crypto traders.After legalisation,the people can use the bitcoin as one of the payment in their shop or industries.
