I think there is nothing wrong with what they do by posting their success or success on social media where there are likely to be many people who see it, because after all what is shown can motivate others or raise the spirits of others who may at that time there are people who are experiencing failure and downturn. And for me the risk that will be felt by people who show their success is nothing more than social risk, or the point is that maybe in the next few days or months there will be many people who come like asking for help such as borrowing money or wanting to ask for directions or ways to be successful like him, and for that problem I think it is not a risk, because after all the name risk is when someone does something that tends to lead to mistakes that can threaten or endanger him such as taking a decision or doing something excessively, but if not then I think posting success on social media is a common thing that many people often do.
I don't know what the lifestyle is like in your country, but in my country, poor people can hang out with rich people, but rich people will rarely work with poor people, and most rich people usually just cooperate and do business with rich people. Therefore, whether someone brags about their success or wants to prove that they have become rich has its own purpose. Some may want to assert themselves as talented people and want to set themselves as an example for others to make efforts as you said. But there are also some people who do it because they are looking for ways to expand better relationships to increase wealth.
In addition, perhaps the security situation in each country is different, and I don't see any risk in someone wanting to brag on social networks when they become rich in my country.
In my country most of them are people who managed to achieve wealth in their lives and then post it I don't know about how and what exactly their purpose is, whether it's for bragging rights or for promotional purposes so that many people or companies want to work with him or her or for something else, but usually I hear that the idea they often say is that they are nothing more than motivating other people who are in the process of struggling to keep their spirits up and prove that the process will never betray the results, and I think it is an idea and action that does make sense to raise the spirits of other people who see it. As I said above, I don't really know the actual purpose but yes, it may be true as you said that indirectly their actions can also be a way to find or open doors for new business opportunities such as building new relationships with other people to plan new businesses. For me the real risk that can happen when someone posts or brags about their wealth is that there might be some people who see it who have bad intentions such as cheating, robbing or whatever.
As for bragging, I think we don't need to post pictures of ourselves holding a bunch of money, or showing off our bank account balance for everyone to see, or ridiculous pictures. We just need to post a little simpler photos to let everyone know that our lives are changing for the better after many hard days without having to brag too much. I think we won't face any risks, people are just exaggerating things more than necessary.
There is nothing wrong with us being proud and wanting everyone to know that our efforts have paid off, our choice was the right one.
In addition, our success is also the pride and honor of our parents, so it is not bad when our parents proudly talk about how successful we have been. Just like in the future, if our children are successful, we will show them off to our friends and be proud of them, which is a great joy for any parent.
