im not smart investor. I am stupid. If I was smart, I'd sell half my coins.. but which of us is smart? Who knew that bitcoin would fall to $ 3500? so no one fool anyone. we people are greedy. And we lost it because of money ambitions.
If you are being greedy then you may face losses so try to be act smalrt and generous don't get jealous of other traders when they making more profits than you,what you need to do is more trades with less profits margin.
