Totally not good. But I appreciate if you can cite the source that explaining how China stop manufacturing of mining equipment. Mining is a vital part of any project especially btc, eth and other big coins that uses mining. However, we cant deny that this crisis have a bad effect on the market, well maybe some miners stop their operation but I still believe some will continue as they know that this crisis will somehow passes by for quite sometime in the future. Do we need to start panicking when this happen? Also if the miners gone, Im not sure that btc will just died out. Of course Satoshi expected that supply will run out but Im sure it will not stop there. Maybe effect will be noticed but hell cryptocurrency project will died out after supply has been depleted.
