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.
There are countless reasons why people sell their bitcoins, you do not necessarily have to be a newbie to sell them, everyone in this forum at some point were newbie and took unreasonable decisions.
Various reasons push its sale: Economic emergencies, basic needs to be met, diversification of investments, tastes, luxuries, etc...
Otherwise, what function would bitcoin have if no utility is granted?
