Although bitcoin has the lowest point but bitcoin still has a very high price, and in 2018 this is the price bitcoin will show greatness with price increases to the moon again.
Technically, the volatility of bitcoin is what makes it reign on the market over the past years. Its value may decrease due to certain events and circumstances, but it would recover soon after. The problem nowadays is that, people tend to generalize and conclude that bitcoin will end soon, which I think is far from happening. Just to give you an example, last month the prices of bitcoin were around $7,500. Currently, its price is sitting consistently around $9,500 and will reach $10,000 soon.
That is why, bitcoin may hit the bottom for 2018 but it still is a good investment option for short-term yield/profit.
Bitcoin prices have fallen sharply this year. I believe that by the end of the year it will grow very beautiful. May be $20,000 - $25,000. Same waiting
The recent fall is very big and it wasn't expected by most. However it can also signify that the upcoming pump to come is also big.It's reaction to the past incident where the rise is also big so the fall for the bottom has been big and luckily it was done. This is now the time for bitcoin to start moving up.
What makes the society skeptical is the media and collective influences from other investors as well. Most newbie investors who do not even know about bitcoin (who just invested without having to search for its background) tend to complain about the recent price drops, where in fact, it is a common scenario in the market. They tend to post threads about 'bitcoin ending in 2018' etc. which makes everyone else skeptical!
The market is promising for the past few days and the price has climbed to $9k and you are talking about panic selling when the market is going strong. We might not hit the highest price this year, but we will have a good momentum at the end of this year and hopefully we will have a big rally next year.
