Signals may be loss but Earthquakes usually occurs in a specific area with different intensity at some point depending if you're near a fault line or the focus of the earthquake but as long as you're far away from it then you're fine and I think that it won't affect the crypto value but deflation may occur and it will also affect the economic growth of the country.
I agree. There is a specific place and faults are the one affected by the disaster. It cannot affect other countries as long as there is internet connection to access bitcoin. Nothing to be scared that we lost access on bitcoin because it will still there even long time we cannot open to transact as long as we have the key.
