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.
It is useless to be jealous because it will only dimotivate you and it will only make you think about other instead of your own profit so focus on your own money dont look at others, being an investors I only says those are real earner who buys low and sell high, without being greedy and selling at panic price.
