Rumors has it that Satoshi is back with a new protocol called Fractal and VTSN as it's coin. This is Blockchain 2.0. No Mining or POW and Use crystal resonance for cryptography.
The movement of 80K btc was a launch of Liberty Money on 4th July, signifying freedom.
Well I don't know about Satoshi being back, but it seems you have come back for your first post, 6 years after creating your account... Welcome back lol.
As far as Satoshi is concerned I doubt he is coming back. Maybe something happened to him. Maybe he died? He is sitting on a fortune and is not cashing it in. That is not normal human behaivor (unless you are some kind of enlightened monk who has surpassed any kind of human desires).
Maybe Satoshi never existed in the first place and it was all the effort of a single/multiple countries to reign in a new generation of money without any backlash from the current masters of fiat?
