I would attribute this to either a hacker, or malicious insider, with access to the announcements before they go public. Not official coinbase behavior. It's way way too obvious for coinbase to be doing this, and if they were why would it be in such small amounts. Twitter is great for getting the pitchforks out. Remember when the news wire was pwned? Someone was selling that news to various investment banks, who would trade on it. I smell a similar thing here. If coinbase were doing this themselves, would it be illegal? I'm not an expert but I don't think so. Still, it's a very bad look and it strains credulity. It could also be dumb luck. The same way people look at successful startups and think that is normal. I'd want to see a deeper analysis before judging.
