If you do want to try to buy on the dip, then I would recommend waiting for a bounce (maybe >10%) just to be sure that it's ever going up again.  Also, you may want to consider buying from me :-) or, better, from a trusted vet here to avoid the coins getting stuck in the current transaction delays.  You still won't be able to move the coins for a while, but at least you can have them in the account you want them in.
