Maybe I'm missing something but how is putting a ban in place that allows public officials to not develop special interests and ruin the government out of greed a "negative attitude" or a bad thing?
Did you copy and paste this from somewhere because the language structure seems designed to mislead and drive a false narrative.
If the government are putting bans in place to stop said government officials from corruption, that's actually a super positive thing and means that Korea is getting ready to fully support cryptocurrencies that they have to put the measure in place now to curb future problems.
