But there are some people in crypto saying that this is all fake bull run and that we are going to see a very drastic drop to 1000$ in 2019 before the real bull run will come and stay
I don't think you should believe it. look at the market looks good, and there is no sign of a decline so far. and I think we are on a bull move that will bring the market up. don't expect there will be big bulls like 2017, this is a different condition.
there will always be changes at any time and we are impossible to know the exact price movements. A bull run or bear market is a situation that cannot be predicted. the easiest is to maximize the use of digital currency. because when the use of digital currency increases, it will grow the value of public trust in digital currencies and this can increase the price of a coin.
