Why you let them to do it to you?

So what are you doing. Some smart guys told you don't sell at bottom. It's time to buy but no you sell when it go down and buy when go up. It's not easy before maybe 10 days when btc go down to 1.8k was thinking what to do. And what I did?
I was buying a lot. I was feeling it go down with purpose to buy it cheap and for sure it would go back where it was and after 4 days it go up 900$. These guys who doing this taking a lot of money and scare new peoples who come into this. I'm wondering how high would be btc if they don't do this.

But i'm not guy who can give you advice in this area so will not do it. Some guys will tell you buy this buy that but they don't know anything. About selling don't let them to do that to you next time when they manipulate price of any cypto. It's enough to be in this few months and see how often it happen. Some guys say don't invest what you can't lose. So think about it. would you invest more than that? Some of you will some of you would't but I have more in this than I'm willing to lose. I see here big chance to make my dreams real. I withdraw more than I invest right now but if all I have go to zero it would be big shock to me and it's not small money for me right now. It's more than 50% of all I have. I will risk and all of you must make that decision. So what would you do.
