Why is bitcoin falling? the long-term bitcoin holders would be selling their bitcoin for fear of an attack with quantum computing that could happen within a few years, for this reason they would be anticipating to get their profits before it keeps falling further? .. the fact is that bitcoin will not return to the price levels of December 2017
I don't think price of bitcoin went down because of the quantum computing, in my personal analysis bitcoin went down because of the bad news come from mtgox can be seen on here
https://news.bitcoin.com/mt-gox-creditors-legal-victory-enormous-assets-to-be-returned/ and the effect of bad news will be done in couples weeks later, bitcoin won't be died just by bad news related with hacking issues and quantum computing.
I think that this bad news too.
We hope price will be recover soon.
price of bitcoin can't fall down lower than 5500 USD.
