Whatever his/her actual reason, Bitcoin is actually more valuable in regions where it is "illegal" to use Bitcoin because it makes use of its main value-proposition. CENSORSHIP-RESISTANCE.
But it's probably a good decision NEVER to tell anyone in real life that he/she uses Bitcoin. Although online, and anonymously - he/she should tell everyone.
If someone lives in China, Iran, or in some region where the government is sort of too restrictive, they can say "I AM FRIM IRAN AND I USE BITCOIN TO GAMBLE, BUY ALCOHOL AND DRUGS. TRY TO STOP ME".
Telling someone about Bitcoin is not a bad thing, it's a welcome idea for Bitcoin to spread to those that have no idea of it, but where the challenge is, is that you are exposing yourself to be robbed, because in my locality, they sees anyone that invest in Bitcoin as a wealthy person, most folks in the streets believes that you can't invest in Bitcoin if you are poor, so preaching Bitcoin to every random person you see is a very stupid way to expose yourself, because you might be robbed.
Personally, and after the stupid permabull advice I gave friends and family during the previous cycle, I'll never let anyone know that I own/HODL Bitcoin or any other digital asset that I may own in the future. I say digital assets because of the possibility of receiving an airdrop of SHFL tokens from Shuffle casino. I play there sometimes and I have no intention to sell those tokens that I may claim from the airdrop in the future.
So if you want to be telling people about Bitcoin, use your discretion to analyze a person first before revealing things to that person that you invested in Bitcoin and give him a reason why he should do so, because a locality like mine, if you exposed yourself easily to the wrong person, you will surely regret in no distance time.
And you know why it's like that? The economy of our country is not smiling at we the citizens, so most people will do anything, even though it's criminal, just to survive.
OR tell people about HODLing Bitcoin anonymously through X or an internet forum.
