Hi there, TC (Topic Creator). I'm pretty familiar with this subject. I've spent thousands of hours analyzing competitive gaming footage (in multiple genres) over the past several years, and I have about 56 competitive gaming #1 Ranks. I've competed in, and still do compete, in "tournaments". Realistically speaking, the "e-sports" scene is obviously new and, to an extent, grass-roots -- but with that grass roots nature can unfortunately breed a form of organized crime, which there's already a very large footprint of right on the face of mainstream e-sports.
Feds have led multi-jurisdiction, multi-COUNTRY investigations into match fixing in the North American division of Counter-Strike, which set many online analysts into a properly directed fit of anger while exposing some of the best players on their youtube channels for fraud, match fixing, etc. It couldn't figure out how to link, but you can just Google "FBI Investigates Counter Strike+Destructoid" to get a simplified article, albeit there are literally dozens of mainstream news outlets that covered the issue. The players just in this simple case were caught red handed agreeing to fix (paid) tournaments, of which they did so in writing like your typical Albert Einstein. If you listen to the head of the ESIC in Australia during his original briefing on youtube with another popular streamer who did a good job exposing the issue, the ESIC leader underscored all sorts of TITANIC red flags that exist in the e-sports community, but in the case mentioned above: it was "outside betting syndicates" -- meaning organized crime groups -- allegedly pressuring the adolescent persons into throwing matches for some extra cash, and match fixing is allegedly very common in what are claimed to be real "tournaments".
Try checking out the incident in physical sports where 11 boxing matches in the 2016 Olympics were rigged, covered once again by not some fringe solo article in hoo haa land -- but a plethora of mainline news organizations. And that's just one of many examples: Check out Pub G Mobile's Twitter account where they feature a list called the "BAN PAN" where they used to ban over 1 million players PER WEEK (on a competitive cell phone game, mind you), for cheating. Check out the news article where Pub G banned almost 4 million players IN ONE WEEK for cheating... on a freaking competitive cell phone game. If you look at it these days it's usually just shy of a million or several hundred thousand people banned (yes, every single week) for cheating.
So to answer your question: E-Sports has evolved into a literal monster with very little oversight, a plethora of cheating (even in paid tournaments, which is a crime called WIRE FRAUD, among various other criminal conspiracies), and mind you that e-sports are often played by young adults or even children. So I would ask the question why on earth, with the billions of dollars involved in e-sports, are the governments of the world basically allowing a form of international organized crime being run by children? I know the answer, but I won't get into it here. But all this stuff is proven because I study this stuff constantly.
"Trades" like the various sports leagues would be fine if E-Sports were actually regulated properly, but that's next phase stuff after -- if ever -- e-sports rids itself of the massive levels of fraud involved. Problem is that match fixing in stuff that involves money has been going on for decades, if not hundreds of years; perhaps thousands (I'd have to trace it back). The way E-Sports teams work is they effectively DROP a client, and said client is then labeled as a free agent who can go whereever he wants afterwards -- so it's already similar to physical sports in that sense. I don't think there's people involved in E-Sports that have the type of value where big trade would be on peoples minds in terms of especially a public interest. So I'd answer your question with a polite "NO"; as it'd be unnecessary -- and state that fraud needs to at least not so darn noticeable, obvious and clear -- for a start. I think that's where e-sports needs to start from here and many other people and companies are getting on bored with this ideology.
Matches are still fixed in professional physical sports (allegedly), but at least it's still beatable if the team or competitor is good enough, and it's not as obvious as e-sports.
