Why would you even care what this dude tries to show off? How lame, another idiot (on the picture) showing off "he made it" likely with crypto, potentially sharing it in some (a)social media context like it's a dick contest. Maybe the car is his, who the fuck cares.
I'd rather suggest to keep a lower profile and not scream to the world you're in crypto.
Those four don't look like some additional Ledger crap to me, but because I wouldn't ever buy any Ledger shit, I could very well be wrong.
Whatever... Not even sure if the picture isn't a bit "dressed up". The angle that dude holds his arm looks to me that the four devices would slip down, but I could misjudge the perspective.
