I would think that the market is contracting due to some uncertainty about the HardFork on Bitcoin, and if Bitcoin goes down it affects most of the market altcoins... So, I am thinking of buying in exactly before or after August 1st, depending on the market behaviour until then. I personally think that we'll see much more days like yesterday having all the crypto in red. I cannot make predictions, so don't take my advise, this is only my opinion. My 2 cents on this...
