My dude, greed is the major reasons why people experience losses, let's leave aside sentiments, everybody is into bitcoin because they wants to make money and in attempt to money many feels like outsmarting the system. The first huge amount of money put into trade and investment was $3,000, what happen I open a trade and leave the market going in my favour, often time I came back to check it, it was still green favour but when it goes a slits against me instead of taking profit and leave, I was believing to hit huge expectations and be like others but the market go against me and wipe all the money, I did not get myself for two months with trauma and shocks.
Most bitcoin investors and traders are too greeding to a fault, wanted to make all the gain in a second, minute or hour without be contented with the little increase you've on your wallet. If we can remove greed we can achieved great.
