At first glance it doesn’t sound bad to tell other people that you own Bitcoin, but there are some details to keep in mind:

Telling all of your friends might not be a good idea

Even if they are your friends you should be very careful if you tell them about your crypto holdings.

As always, there are also those who quickly become jealous, especially if they think that you are rich (but you aren’t) and start begging that you could give them some of it. This can lead to distrust and a previously good relationship can be permanently damaged.

Or in opposite, we all know some of them can’t keep a secret and tell it others and they are telling it others again. Then, it’s possible that people get to know about it, who are jealous / have a bad relationship to you / or are just criminals and plan a robbery to get your crypto.

After all, the more people in total know about your holdings, the more likely it gets bad people find out about it.

Linking your identity on the Internet to your real identity can be very dangerous

It’s generally not a good idea to use real names on the Internet, especially when it comes to cryptocurrencies. This applies to forums, public social media accounts related to cryptocurrencies as well as for all services, where we have to use an email address or similar.

Since an email address is always required to register various accounts, you should use a newly created email without your real name. This protects against spam and also against scammers who want to find out your real name and address.

Using social engineering, scammers could draw conclusions about the person, how much crypto they own, find out where they live and plan a robbery.

KYC can also reveal your identity to people that shouldn’t know about it.

There’s a big misconception between the purpose and the result of a KYC-procedure.
It’s very important to be extremely careful and know the risks of doing KYC. Better avoid it if you can and don’t want to have bad surprises. It’s possible that the KYC-Scammers / Hackers use your stolen / hacked personal information to gain knowledge about your personal address or location / sell it to others and they can plan to rob you at home and steal your crypto. Even Coinbase was caught selling user data.

Here are a few more reasons why doing a KYC puts you on a big risk: Why KYC is extremely dangerous – and useless

Overly careless handling of personal data increases likelihood of being victim of a $ 5 wrench attack.

There are various attacks from which you can lose your cryptocurrencies: scams, phishing sites or hacked wallets. Another avoidable attack is the famous $ 5 wrench attack:

It can be avoided effectively if the attackers don’t know the personal data and where you live.

Finally, it's up to everyone to care for their own data and who will gain knowledge about your crypto holdings. As a basic rule, it is always advisable to be careful when in doubt. This also applies to all actions on the internet that pose a possible threat to privacy.
Once information is revealed, we can’t make it unhappen including all (bad) consequences.

You can say that same about you cash money, whats the different Huh
