Opinions on the future of this

Curious to know everyone’s opinion on the future of this Chinese 5th anniversary box! As most of you know, it has a bad arse Pikachu promo and a few other goodies including a booster box, I purchased for $270aud and its since skyrocketed to $800aud plus! Is this the top? Should I be hanging onto this for longer? Would love to hear everyone’s opinions.
