Best thing to do is to buy your Bitcoins a portion at a time, if you believe it will still go down don't wait buy 20% each week from now till August one, so that if it doesn't go down you have some and if it does you didn't purchase everything at the same high price and if you believe it will also rise do the same, don't buy everything now so that if it goes down you have a chance to buy at a cheaper price .Reduce your risk exposure.
