Will this encourage trust and investment or its just a way to bring crypto under surveillance and regulations?
For now, neither. This is just an union voicing their opinion about what needs to be done about the blockchain industry and how it needs a regulatory framework. Depending on how the korean govt reacts to this, we can discuss whether it will encourage people to invest in the cryptocurrency market or not. But knowing how pro-crypto South Korea is, I would expect some positive news in the upcoming days or weeks about this whole thing.
Is it good news? Well, it is good that even the South Korean lawyers are making an effort to help establish a regulatory framework in the market with help from the govt.
