Bitcoin is not well-known in the country where I reside and no business accepts Bitcoin. Which means I will join any celebration on social media or the forum. Maybe I and a few Bitcoiners I know in my location would consider starting an event to make the yearly Pizza Day celebration. My main problem is the government's negative view of the crypto industry. I am concerned that they might see such an event as an avenue to promote Bitcoin and find it offensive. Another possible problem might be the negative perception that people who own Bitcoin are rich. People who attend such an event might become targets for scammers and other villains.
these are all very valid issues. Of course you don't have to discuss how many you own, but I understand that if you're promoting it, it seems obvious that you've benefited.
Best I can recommend is to have cold storage in a secure location OUTSIDE your house.
It's rather ironic how bitcoin sometimes is branded as "be your own bank".... but then it's a lot of work to be your own bank... and there's a reason we have banks... it's cuz they do provide a server, haha.
Anywho, be sure you put most of your bitcoin in secure storage... Anything more than you want on an exchange to trade with or in your wallet to spend.
Good luck! hopefully, as more governments start to use it like currency like El Salvador, it will continue to be seen for the legitimate uses it can be in addition to the bad ones...
