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.
Bitcoin have a price because sell and buy transaction. If everybody holding their bitcoin and nothing transaction on market, i think there is no price on bitcoin. Some people selling their bitcoin because many reason and some people buying bitcoin for profits reason too.
Maybe some people selling their bitcoin because they need money or maybe just want to trade to double their bitcoin by buying the dip
