Everyone in here is desperate to convince each other the Bitcoin can only go up and therefore you have to buy and hold.
But when you buy Bitcoin, someone is selling it to you.
Why are people selling Bitcoin?
The knowledgeable people are the ones who are now slowly selling out before the bubble bursts. When you are now buying more and more Bitcoin ("investing" as people in here call it) who do you think you are buying them from?
You are buying from the knowledgeable people who are slowly getting rid of their Bitcoin.
Everyone has their own personal reasons why they sell bitcoin. May be they are just in the need of money or want to try something different. We can't blame them for quitting this early. Let us just hope that in the end, a lot of people will be successful because of this. And whether you hold or sell, bitcoin will still remain because its primary goal is to improve our economy and it is starting to do it now.
