@cypherdoc I very much doubt he's Austin Hill, and he's almost definitely not Gmax (Gmax wouldn't post links to mises.org as some of his account's first posts, and he wouldn't be so into supporting hodling; brg444 is a major Bitcoin bull and echoes a lot of the kinds of arguments we make here on that aspect of things).
As to why he's not Austin Hill, besides the obvious that a VC like Austin Hill wouldn't have that amount of free time, look at the hands:
↑ Austin Hill
a month ago. In contrast:
From
here in October 2014. Google image search shows
no other copies of that image on the net (likewise with
tineye), which suggests that's his own photo. There's no way that's the same hand unless maybe Austin gained a lot of weight in the last year. But even back in April his hands were pretty pudgy and overall he's quite portly in a way that would take longer than a few months to gain:
I think brg444 is just an interested party who was probably radicalized by the initial face-off with you (cypherdoc) about sidechains and turned into a Blockstream aficionado. Big clashes like that have a way of entrenching people's positions deeply, especially if he is 24 like he says (same as theymos I think). There are plenty like him, he just seems particularly avid as again he's a major bull and apparently sees Core/BS as the way forward.
