IMO BTC is going to continue to trend down and settle around a range of $4,500 to $5,500 at a new psych level. Reasons are slow adoption world wide from other countries than Japan and growing competition from alts.
Why are you scare if that will happen. That is the good time to buy more bitcoin if the price reached the 5k mark, slow addoptions and regulation about bitcoin has a huge impact to its value, the only thing we can do right now is to hold and believed in bitcoin.
