Iam also think btc price bring come to 4000$ or 3500$ value with this bad marketing condition. But i not sell my btc or altcoins now. Iam strongly hold my top coins till 2020.
Yes, the market is very unstable now. Maybe we will have a big regret if we sell our coins now. Holding is the right choice now. If the price fall to low, we can should choose buying more instead of selling to cut loss.
