According to my opinion, the Alternate cryptocurrencies Price will down for a while because ETH and BTC getting strength in this month. If we look at the depth market in all exchanges, especially Altcoins/ETH or Altcoins/BTC, you will see the contrast, supply and demand is not equal. Most of people converted their coins to ETH and BTC.
as you show in your images, altcoins will be falling, this is for BTC raising if you check the market when BTC fall or raise, Altcoins falling. because people invest on BTC at these times.
