This is what OP didn't mentioned but I am glad that many have mentioned this, patience is a must for every investor.
Investors by nature are impatient and that often leads to first time losses in trading. Eventually the consistent and diligent traders will understand this and stop doing it.
Then there are those people who are rare but have good patience and are able to keep calm throughout events - for them bad times dont matter much and they are able to execute trades efficiently. We should try to be like them and learn from them.
Dont give away money to exchanges just by being in a hurry.
