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.
Here is some examples:
HitBTC Market:XMR --> BTC

BSTN --> ETH

What do you think? Lets we discuses more. Cheers
Again back to form in Bitcoin and Ethereum so know only market is runs in the normal way. Because number of altcoins are available in the market but many good altcoins are growing fastly so shitcoins are not survive in all the time. Still many potential altcoins are raise in the Crypto market I think you are not understand the Crypto platform road map it is move to the right way.
