Cap Transfer prices at launch

It's crazy to me how I can play, complete objectives, over 3-4 days and have around 10k coins.  Yet, I see players being purchased for 200-300k and over. some teams are worth millions of coins already. How are these players getting 200-300k (11x) coins in 3 days?  There was a notice on the game that purchasing coins through 3rd party services, and illegitimate transfers would face consequences.  So, I'm curious to know how these players are getting a million coins 3 days into a launch.  Obviously people can pay hundreds or thousands of real dollars to get tradable packs and sell players on the transfer list, but I believe there should be someone looking at how these players are accruing the coins to buy an entire team of 200-300k coin players this early.  The game hasn't even officially launched.  So why not make it impossible to sell anything over 20k.  That could make this game much more competative.
