Lot of noobs traders , don't control their emotions and make worst mistakes : buy at high price and sell at lowest
how to control this ? = put orders (buy/sell) and close the platform
Indeed. "Buy low, sell high" sounds very simple doesn't it? But I think most traders actually do the opposite. They often buy in when the crypto is on the rise, and sell in on the way down.
How do you control this? Plan your trades. Decide on and set a certain price where you're planning on buying. Don't let your emotions take control of you.
Also, be active on bitcoin news. There are tons of websites that can provide that. Google is your friend.
