- Not having a target when trading: When trading, you should have a target as soon as you enter a trade, and as soon as your target is met, I believe you should exit the market. Most people have lost money because they don't have a target. Some targets may be met, but greedy people will refuse to sell, which resulting in a loss.
This is important to trading yes because it is like moving a truck to a place or down the road and you have to be careful about it to get to where you going but regarding to trading, the challenge is greed. I see sometimes you wait to grab bigger profit but at the end the market traps one to losses and unfortunately you begin to regret...A good lesson to learn.
- Entering many trades at once: As a beginner in Cryptocurrency, you don't need to jump into many trades at once; instead, focus on one or very few trades that you believe you can monitor. If you have too many trades open, you may become confused and lose control of them; however, if you focus on just one trade, you can give it your full attention, whereas if you have too many open, your attention will be divided.
IMO this is not a problem. Entering more than one trade at a time isn't bad but what is bad is a martingale without a stoploss applied to each entering
- Not using stop lose: Some people believe that using stop lose is a waste of time and money. While I understand that not everyone is interested in using stop lose, I believe that as a newbie, you should make stop lose a priority in all of your trades because it will help you cut or reduce your losses if things go wrong. However, as a skilled trader, you can trade without using a stop loss because not everyone prefers it.
The most important part of trading is to use stoploss which is part of money management skill. A skill trader not using stoploss has his day of reds.
