I would never say Bitcoin will reach any level. I have no idea if it will ever see $6k again let alone $20k. That's why I laugh and scoff of the so called experts predicting $1 milly and other outlandish levels.
All these "experts" are players as well and it is in their best interests to make statements that favor their interests. Jesse Lund? Vice president of Blockchain and Digital Currencies at IBM He sees Bitcoin at $1 milly. Does he have an agenda? The Vice president of Blockchain and Digital Currencies at IBM?
I'd say so.
If all things were held constant Bitcoin "might" be more predictable, but with Gov'ts, Central Banks, and the IMF (which has had its own currency queued up and ready to go, in fact, they have already tested it) all looking to profit from the technology we, the retail investor, do not stand a chance of knowing where tis is going.
