I have a few guesses. The bitcoin Segwit coming Aug 1st could cause concern. There are a lot of ICOs coming and people are making a lot of money from them. People could be skimming say 10% from gains to play the ICO game. Also, quiet week for news on war or N Korea shooting missiles, etc. Part of the rise in cryptos is from China, Korea and Japan trying to protect wealth. I really have no idea, but if bitcoin goes smoothly on Aug 1st then maybe we get upward momentum again. Following you now.
