hello friend,
in 2017 I was very happy when I saw the price of Bitcoin increase in coinmarketcap because when the price of Bitcoin increases, then the price of Altcoin will immediately increase too, but for now when the price of Bitcoin increases and it does not affect for the prices of Altcoin (even still down), then when the price of Bitcoin goes down and at that time the price of Altcoin will go down too, so I do not understand the current state of the market and what is happening right now.
The happening right now market are still not stable especially the bitcoin price 2017 bitcoin price is so high then so fast to down that is why give a big effect on altcoins too. Maybe now bitcoin need to recover that but not so fast is taken slow. We must have wait and have patience for that time to increase again the price of bitcoin and also altcoins.
