People are panicking with free trade that their items are going to lose value. If I were you..
1) I wouldnt get a bgs
2) I would wait for prices to stabilize.
Your choice though.
REMEMBER after the update, there will be no G.E. low-mid-high prices set anymore! They stated that on their website before you choose your option to vote.
Prices are going to go everywhere and are going to take a long while to balance out "IMO". I'm going to invest in some small stuff as well. Such as sharks, drag daggers, prayer pots, super attacks + strengths.
