Incredible!

But is there also a chance that bitcoin goes to zero?

I read in an article somewhere that at the moment it is more expensive to mine a bitcoin than the value of that bitcoin.

In my idea this could mean 2 things: nobody is interested in mining of bitcoin anymore and the value will go down, OR miners will start to higher the prices. gradually in step with the price of the mining and hiogher...

It could be then that people will follow and your scenario might be true.
