Trezor said they'd consider it (but never looked into it further) while the ledger rep I was talking to asked what I could do with a $500/month marketing budget. lol
Any company would never know the benefit of marketing in the Bitcointalk community unless they have tried it at least for once. I wont blame them, they don't trust their instincts when it comes to marketing their products. If not for anything the entire companies that has run their marketing in the forum are not stupid, if they don't see the benefit they wont do it in the first place.
$500 per month budget is too small. Did you give them a response or you just ignore the conversation?
