He is not looking to kill it, he is trying to impose the DAME tax, DAME means Digital Asset Mining Energy, and the idea is to start with this tax from 10%, then 20% in the next year and 30% on the 3rd year.
So, the plan isn't to ban the mining, but with those huge taxes, no one will want to mine there. Is not a good business. But i don't think congress will let that tax come to live, and if it does, they will stop it before the 3rd year, because other way people will start creating illegal farms.
Don't you think people who are mining bitcoin don't mind relocate to the country that is more favorable because I believe this isn't the sole purpose because for him to keep increase tax every single year shows that it's indirect killing therefore when it's much on people those who don't find it favorable don't quitting, and if he sees that people still instigating then he would have to turn the other way round just to make sure he entirely eliminate it.
Its like he say it take it or leave it since you don't have a choice since I am the one who have authority to implement something that I like to happen. That's why I think maybe its good for miners to leave on a country that doesn't give any favorable chance to do a legal business. There should be a country that best accept this operation and for sure for migrating they can escape those heavy regulations made by those abusive government.
What they do is somehow power tripping since they really want to eliminate some industry that they maybe don't understand or hard to control that's why this people throw up something bad implementation and leave those people doing good business no choice but to swallow what they want even if this is against on their will.
