If a loss has occurred, there is not much that can be done, a loss is a natural thing to happen to an investor, we can only realize and believe that we are able to recover from the losses we have experienced, because from the losses we experience, we can learn from mistakes. what we do and it can be a lesson to see the opportunities of the next victory.

How do you lose a big amount of money? Is the price of your coin decreasing? Or, do you just sell your coin at a cheaper price? If you are still holding your coin, just wait till the price increases again. There is no need to be panic because the decline in price is something normal. But if you already sold the coin at a cheaper price, there is no chance to deal with your losses. Just focus on your other coins to take profits and don't make the same mistake.

to manage losses, we must place a stop loss according to our risk calculation, or if not at least we calculate the amount of risk by doing a cutloss. so that the capital we have will grow in a healthy manner, either loss or profit can develop healthily. for the amount of risk for each person, of course, will be different, this depends on the analysis of each. and most importantly we must be disciplined towards analysis, whatever happens

Actually those what you've mentioned above they're all the most important things to know when it comes trading, but there's something missing for me, which is the emotion, i mean you should not trade with emotion because that's the common problem why we always made mistakes and regrets afterward in trading.  Indeed its useless if you know all the important stuff to succeed but you don't know how to control your emotions especially when there's a bad situation in the market the occurred . So add that one to your list to avoid mistakes and to have a good journey in trading.

what does "future" mean on your idea? 3 months later, or 10 years later? sometimes you just got lucky by choosing one or two top coin on the market, so there is no need to check for long-term potential. i'd say you should check out those threads about top coin first if your goal is to find hidden gems. no need to create new threads for this.

You have all of those but in the end, you'll still be having bad experience due to the situation that you have to deal with. Even the best traders do also feel panic and they cannot contain it.
No one is exempted with that when you trade because it normally happens whenever we see the market isn't in the shape that we want to see.

When market conditions like this are necessary for us to be careful in trading. This could be a trap that will get us into a trap if done with explosive emotions. Investments must prioritize analysis and patience. For now, long-term investment choices are not appropriate in my opinion because prices are in an increasing condition.

That's correct. But it was just the basics of investment.
The crucial part is when and how? If you decided on a short-term investment you should also have a plan on when you will withdraw it.
The same goes for long-term investment. Make a date, put it in memory.
You should also not resist the withdrawal even if you see pumps happening left and right. Once you start to defy them, all the plans will not work out anymore, you will get used to it and it becomes a bad habit.   

Good start with the  trading mate. I am not sure if you are trader or you just putting up your thoughts here but these are the two terms every potetnial trader must know and learn to act accordingly. With my experience I have seen people go crazy about the long term trading. The reason, it's kinda  difficult to hold for very long time when you see the bitcoin market is fluctuating at alarming rate. The number one reason behind people sell before the timeline completes is their greed to book the profits. That's even good thing but the exit strategy could fail when you see that the bitcoin or other crypto has gone way further than what you sold at.

To avoid such pre-matured sells is kinda tough thing. Every trader fails at this and in turn do not become the long term holder. But, believe me crypto is an asset which can give fruitful results if you hold them for very long period of time. I mean come on, few cents invested a decade ago are worth 45K USD today. Lolz.
