With recent surge in Bitcoin above $5000, those prophets and prophetesses has come again to predict. All there predictions in late 2017 and early 2018 that Bitcoin will not rest and gasp for breading until it reaches $80,000 per Bitcoin failed to hold any ground. They have lead millions that are following there channels bankrupt in which they are yet to recover. That is why it is good to always do your own research and follow it strictly, even-though it failed, you will be more satisfied than shifting blames to someone that is directing your decision financially. I have found out that majority most times are always wrong.
Why all these stories, they are silent for over a year and suddenly re-appeared about a week ago. Now, there prophesy is that Bitcoin will re-traced to $4200 before we experience any tangible moves, telling there followers to place a pending order around that range. Personally, I don't agreed with them but have an opinion that they will join to buy in $6300 - $6700 range. Technically, on which side would the shift goes based on your justification.
Most of the people will just go with the trend so if they are seeing good price movements on the bitcoin they will say bitcoin will reach this level in this time period and so on but if they see price decline they will say this is the end of bitcoin so just quit now,if you are a true believer you no need to worry about these short bumps as well as dumps just bee on the side of holding.
