2018 did not show such growth as in the previous year and if you think objectively it is unlikely to bring, but I think that the market will begin to gain momentum by the end of the year or early next year.
Hopefully it will be happen in the end of this year that the price of btc and most of altcoins will increase and more valuable. In my observation in the market, it is too difficult to coins's price, example like btc to reach its price like in the end of 2017, but everything is possible in the cryptocurrency and of course i still optimist that the price of btc and most of altcoins will increase drastically. The increasing of coins's price still possible in the 2018 because we still have more than 2 months to end this year.
