I do not believe in anything like that. many experts say if the year 2018 bitcoin prices will be very high, but until now there is no sign if the price of bitcoin will rise.
Yup, There's no guarantee bitcoin will reach that far, but it depends upon the investors, As observed in the present, Bitcoins finds hard to recover its peakest value, Remember December 2017, It smoothly climbs up to 20k, and now it struggles down to 7K, This is the biggest bubble ever happen in history.
It is very normal for BTC to change, we can see that the BTC has been going down continuously over time, many investors have been afraid when the BTC price drops, but I do not, I do not Fear what, I believe BTC is the safest coin, we hold them can only be careful to prevent hackers. Do not worry about the collapse of the BTC.
