lol, zero.
How can a decentralized peer-to-peer currency reach zero?
The whole point of it being decentralized and peer-to-peer is so that there aren't any people at the top influencing decisions that affect the price. Such as the publishing of quarterly financial results. No people in the middle or the top running the business, affecting the company's stock prices.
There is no company, it's Bitcoin. For it to reach zero you would have to simultaneously take all exchanges down, convince everyone to stop running Bitcoin networks, including the average Joe at home that runs a node by having the app connected and running, whether they mine or not, also convince everyone to sell their coins, and then also somehow take all those coins they sold, and destroy them, somehow. All simultaneously or within a few days at least.
The price is dropping a bit now, however my point this whole time is that is has had an upwards trend, and a month ago it was on the rise to a price lower than it is right now. I've posted graphs before, I'm not going through it again. 2 months ago it was on the rise at $42,000 (we're talking US dollars here), rose to nearly $70,000 last week and now the market is correcting itself, as it has always done.
Selective bias is what I get from this thread, but then again it's easy for any any detractors to claim the same thing about me. The facts are there. What people choose to believe is up to them.
However I still stand by the point I made a while ago:
I had someone else the other day tell me "Bitcoin only has value because people believe it has value", they didn't want to talk after that because I said something about "keep reading your Bible" or some shit. I can't remember.
