It seems like no one really can predict the future and know what will happen. It might raise and it might fall. But in my opinion, since there are many altcoins in the market which have a strong potential in terms of future growth, we should use this opportunity to buy altcoins and hold them where uncertainty caused the price of such altcoins to be relatively "Cheap".
Coins with strong potential will shine one day regardless of what happen on 1st Aug . So, probably take this chance to diversify and keep some cheap coins out there! Cheers!
