Here is a snippet from a message FZ sent me in April 2017. I asked him how he predicted major rise in altcoins in March of 2017.
ME: How did you know altcoins were to rise mid March?
You turned out to be right, although they seem to defy laws of gravity and refuse to go down
FZ: Well I didn't expect this level of fiat pump; so technically I was wrong.
Most likely in a year or two; it will become clear how I came to that conclusion. Sorry I can't be more forthcoming. To answer your question I would need the permission of others; which I find unlikely in this case.
I was planning to ask him in March of this year to be more "forthcoming" about this mysterious claim.
I guess we will find out "in a year or two".
RIP Fullzero.
