"DON'T BUY IN ALL TIME HIGH!"
Yes, this is one of the common mistakes that most newbie are doing when it comes to trading.
I admit that I'm a newbie when it comes to trading, but this is one of the additional good experience that I have so far.
Nothing really bad as long as I don't panic in what I did. Now, I need to be patient to wait it will go back up.
What I forgot?
Forgot about checking the volatility to check.
Forgot to think that it is still too early to buy.
The lose of 15% in just 12 hours is really a big deal.
