Bitcoin is now down at 5500 dollars. This is not good in cryptocurrency because bitcoin is the foudation of all cryptocurrencies. If it will goes down, expect that other altcoins will follow it too. Look at Ethereum and EOS, they move down after bitcoin goes down today. Will it be move up on upcoming years?
Yes. All the other altcoins are dependent on BTC and whenever the Bitcoin prices crash they crash even more steeply. I just checked the Coinmarketcap table. Out of the 100 top cryptos, there are only two which are in green (Nasdacoin and Dai).
