I believe in that bitcoin will always survive and will go up whatever it happens, but the market is not on a good condition and everything is being affected now
Bitcoin dropped from 20k$ to 6k$ due to some major decisions taken by US and other powerful countries but now people show their interest towards bitcoin again so we will see bitcoin will reach 20k$ again. Bitcoin start growing because investors from china and japan show interest to invest in bitcoin in coming days and some of them start investing in bitcoin. So if you really want to get profit in future then buy bitcoins and hold them till the end of 2018.
