Hi there and thanks for your post dude !
You have a very optimistic vision of what could be worth the Steem coin at the end of the year, and I am too ! However, market fluctuates and sometimes storms happen. In that case, FUD (Fear, Uncertainty, Doubt) is extremely powerful and people tend to sell their coins ASAP.
The opposite is also true : I was burned when I first started trading, when I would hear vast numbers of people in a group for a coin saying “This coin is going to $1 USD!” When you see enough people yelling it, it reinforces it in your mind and you start to believe it. And at this point, FOMO (Fear Of Missing Out) starts to kick in, and people tend to invest in that money.
You said it, the market fluctuates and your money can increase or decrease.
If you missed a rocket, you can still catch another one ;)
I'm just saying that overall, holding through storms isn’t a bad option.
We all made mistakes when we started but you learn. And yeah there is always another opportunity.
