I think this isnt fall ör down. The increase in 2017 was already a precursor of this.
So this level will stay, it is normal for bitcoin price.
Its being long that 2018 had entirely passed and market remained o the downside. Now 2 months of 2019 is going to get over shortly and still btc is at 3500$ levels. We will require some push to happen so that it can take upwards towards 5k levels and more which will get more and more people to join back again this rise.
