In my opinion the price will rise but only 0,12$ or less. I think that many mine and crunch users will join and only few mine and hold, reducing the current participation of total mine and hold users, but the price will rise anyway per old users and new investors.
Anyway, I see the team requirement a technical limitation, so it should be removed no matter the short-term price consequences. But this change should be announced for a while before applying it, because it is an important POW change so people should have time to get ready, the old users for the difficulty increase and the new users for start Gridcoin mining.
Removing the mandatory team req won't include the entire BOINC community immediately, so your mag will be the same except there will be more users joining the NN each day & mag will likely decrease due to competition.
