But what would happen if the oldest and most valuable asset on the market, Bitcoin, dropped to zero?
Such thing would happen only if an unrecoverable and very big problem would be found in Bitcoin. Until now no such thing has happened (the big problems were early and recoverable), so we can say it has already passed the test of time and 0-value scenario is pretty much unlikely.
However, was this a genuine question or just some attempt to advertise a website?
Obviously it’s more on the advertisement of this website he posted. But anyway, bitcoin will never reach zero value if there will be no world events that will leave huge effects on its price. Although the market had experienced a lot of struggles because of some inevitable events but all those have only come and passed, and up to this moment, there are still no reasons that bitcoin will end up being useless and end up in zero value.
