For me, according to my experience in trading, before starting in this field you must learn and understand the basics, they will be as the following :
1- You must learn how to read the market smartly:
Maybe you need books ( like, cryptocurrency the trading bible..) to learn more about cryptocurrencies , you should also learn how to analyze the different situations ( dump and pump..).
Be careful: Do not trust in the news by the media, because they are always manipulating the traders through some fake expectations.
Important information: When you read one book in every month, then after 2 years you will be in the TOP 10 of the most successful man/woman in that field.
Yes, reading the market is very smart, however it would be very difficult at times because of so many news source and just what you have said, you need to filtered out everything and not just come into conclusion. This what's separate newbie traders from more experienced one. Newbies tend to be swayed by every negative news and react swiftly without looking at the bigger picture.
2- Strategies and tactics:
You must deal with situations through strategies and tactics ( Plan A, Plan B) .
"Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat "
- Sun Tzu
Strategies is based on the market situations. One simple strategy is if everyone is selling, then you should hodl and also buy more.
3- Take the risk:
In my opinion, the risk is essential to every big profit, and trust me, when you play it always safe, then you will earn a little money in trading.
Of course big risk, big reward. There's also such thing as calculated risk. You can even do diversification, so you can also protect yourself from such high risk that may not turn in your favor at the end.
You must to control yourself, and be patient, especially in difficult situations like, big crash.
"Patience is the key of success ".
Good luck to evey trader .
No need to put emphasize on this, as we have been spreading this old adage in this forum for a long long time. Sadly though, there are still investors who don't have control of their emotions, so instead of maximizing their profits, then ended up losing more.
