Sometimes acceptance will bring also different disadvantages and one of it is the tax that will definitely favor the government while lowering the income of the traders as the fees of the exchange will surely increase.

Legality is good so we don't need to hide from the governments but our freedom will be ruined as the government will surely create new laws that will help them to monitor all the crypto users in the country and tax all of them in every transaction that they will make. I am not that sure whether filing a petition will help the traders in Korea as it is very difficult to fight a government if you have no solid partners to push through the petition.
