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.
I think you shouldn't panic, this is the price stabilization phase for Bitcoin. As you can see Bitcoin is still the king of the cryptocurrency market, it needs a lot of time to stabilize and grow. I believe that in a few months, Bitcoin will be more stable and its price will surpass $ 15,000. This is a good time for us to buy Bitcoin and hold them. Besides, we can also buy some potential altcoins such as Ethereum, Tether, Litecoin, EOS.
