Given your results, and a quick glance at those names on sharkscope (poker player tracking site), your big win wasn't even in in the past 2 years, it was back in 2012, so your post is pretty disingenuous in that manner, additionally your name nomaldiagram is your most recent trackable name, and it's down -$8k. Linking to 1 decent score, + a few small wins over a 5 year stretch is pathetic, and I doubt you're a pro, or particularly good at the game. Perhaps you're very personable, perhaps you're great at building a fan base, perhaps you've got some skills that could make you a better option, but given what evidence you've shown thus far, you've got nothing. So the question is, does Dash want to pay someone who might have won $50k or something over 5 years, $15k+ per month to promote Dash? Poker, is not an easy game by any means, but poker in 2012 vs 2018, are two very, very different things, tons of pros have been forced to quit because they couldn't keep up with the game, and I highly doubt you're any different from that. Showing results from 2012, having losing results in 2016, and having no other evidence for any of your claims, makes the decision here simple.
Now, what would a good poker twitch streamer look like, and how much would they be worth? I don't know how to quantify that last question, but a good poker streamer on twitch who would be a solid brand ambassador or whatever for Dash, would be someone who already had a large following on twitch, and averages a good amount of viewers when streaming. Almost certainly, they'd have to play on pokerstars, because that site has the most traffic by a huge amount, thus only streamers on the site pokerstars.com, actually get decent amounts of views on twitch. Most american poker streamers get single digit, to low double digit average viewers on twitch, which is basically just crickets, and that usually takes them a while to build up, even if they're actually good at poker.
Given all of that, I am incredibly confident that this would be a complete waste of money, and almost any twitch poker/dash combo would be unprofitable and a waste of time, unless the player already had a built up fan base and an amount of viewers that makes sense for the price being asked.
In case this comes up again and I don't catch it, to be clear, if someone wants to be a twitch poker ambassador for Dash they'd need the following things (in my expert opinion).
1 - They'd need to play on Pokerstars. No other site draws in anywhere near as much attention, because no other site has anywhere near as many players.
2 - Their fanbase must already be established, and large enough to warrant the price they're asking.
Without that, it's a waste of money. (edit - also, to be clear, as someone who has >500 dash and also plays poker professionally, it offends me that someone with such results would ask for so much, which is why the language here is perhaps harsher than is necessary, I'd value this actual offer at something like 1-2k a month, and it'd still be a waste of money)
