China could try some maneuvers to take advantage of controling most of the mining and owning most of the markets? Yes
Could it hurt Bitcoin? Yes.
Could it destroy Bitcoin? Probably not.
Also, If you own most of it, why would you want to hurt it?
I think the point now for cryptocurrencies is much more about how to popularize it for common people and common markets and not only for people that are somehow related to programing or technology.
My best shot would be a strong, anonymous currency that could be mined by people without them having to invest in new techs and super equips every year. I mean decent mining on phones or even when you are doing some stupid exercise in a gym.
This, along with nice GUIs for storing, trading and mining would make people want to use cryptocoins in their local business.
China has absolutely nothing to do with it unless the fact they have 1/6 of earth's population so is pretty ok to expect that there are more chinese people in anything thats international and online than any other nationality in the world.
Bitcoin will die if it cant reach regular peoples houses for some time from now and for this to happen, i dont think the chinese would have much more to do about it then other people from other countries.
Its not about who mines more or trades more, its about if people are using it or not.
Whithout Chinese megafarms maybe our transactions would take ages to confirm or maybe Bitcoin network would not be able to grow.
The more people trading bitcoin, the more miners we need.
So if theres something that can kill bitcoin imho, its not a nationality, but the inability of the coin to make itself popular and mineable along regular people, not only TI and technology fans.
Exactly. We jave to remember the bitcoin in the first place is a peer to peer type of technology so a certain group can manuever it yet cannot destroy it. Chinese government is taking actions with regards to chinese fsrmers which is i think a gopd time for common miners to perform better.
