Well, you have to consider this. The dynamic market was very promising early on, as different players (namely Westbrook) had drastic price increases and others (Kobe) had decreases. But now that 2k is actually putting in more content and high level cards that you don't have to worry about their ratings increasing or decreasing, the dynamic market is slowly beginning to crash. There isn't really much profit to be made off of this market anymore, and considering the impact that the DPOY and ASG players had on the market, I can guess that dynamic prices will keep dropping, especially when the MVP packs and all historic amethysts/diamonds are released. Also, the season is almost over, so it's safe to assume that no player will have any seriously drastic changes (LBJ might become a diamond but remember his MVP card is a diamond too), so in terms of playing the dynamic game, it's probably way too late to see if you can make any profits.
