I think the cause to this "rush and sell " is the lack of knowledge about what you actually invested in, bitcoin should never be seen as a get-rich-scheme because its actually a currency and was created to solve the issue of centralized money system in the sense that you can actually be the bank to your own money but overtime it has gain fame and popularity due to its increase in value which many people who has and had the knowledge are still benefiting as an investment means.
@Mr.suevie, some people who sold cheaply or due to volatility pressure did so for Many reasons, although there are people who sold because they had a vision for short-term investment, and some were scared because they thought their asset would melt because of price volatility. Some people also borrow the money they invested with, so they can't stand to see the money dip, although all of these attitudes circle around a lack of full knowledge of what they are doing, just as you said. I told my friend that a successful Bitcoin investment is based on the level of knowledge you have about Bitcoin and also on your source of information, because on the internet there is a lot of confusion and misleading content, but the BTT forum filters it out once such content is brought here, and for someone who is not on this forum and is getting information from the wrong source, they could get misled.
