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

This situation is normal and always happening from the start, a lot of factors why this is happening, but eventually if we look at the on the previous history, the same pattern goes on., which is not surprising to me, a few months ago, all coins are so high in prices, then lately this year it goes down almost 60% in fall of prices, ive find it hard to recover the losses but i tried to understand that this is not permanent, and all things are just ordinary, we just hope everything will be normalized later on.
