Anonymity on the Bitcoin network depends heavily on our actions, so I would not recommend relying solely on the tools that can be used in the Bitcoin protocol. Before doing anything, think about what it might lead to in the future. Do not disclose that you own Bitcoin and do not link your wallets to your identity, and then the likelihood that someone will hunt for your savings will be minimal. The same applies to fiat money, but unlike extortion with fiat money, it is much easier for an attacker to hide with the obtained Bitcoin than with fiat money, including cash.
I do not understand how someone can link their wallet to their identity in real life? If someone really says in public in real life (I don't mean forum where you can be anonymous) that I own Bitcoins and this is my wallet, then this person is stupid. If you just say that you own Bitcoin, then no one will know your wallet unless that person works in an exchange that you use and has access to the all the data but majority of us here use Electrum, some of us exchange coins through decentralised exchanges.
In my country, lots of people no longer use cash and the security of online banking is really high if you want it to be. Banks also have good insurance for customers. Banks here are doing really well, two of local banks here have one of the best UI/UX designs in the world.
As much as possible on which you should be that discreet when it comes into the money that you are owning whether you've been that having tons of cash, or having tons of Bitcoin or crypto. Nothing beats out into those individuals who arent that tactful into their holdings or on how much money they do have. It doesnt matter whether on crypto or with fiat on which being silent would be that putting you out into those potential problems like being abducted or being that kidnapped or what and we've seen tons of situations for those crypto people who had been that into such experience and this had been done physically or in person. In speaking about into those people who are just that behind their screen on telling about that they have tons of coins, even if you do say that they wont be that easily be that being traced up but still we do know that there are those scammers or hackers that could potentially be that lured in into those people and ended up on getting scammed or hacked with having that little to very least possible information leaked on a certain user or individual. We do know that there are some people who are that being that too careless when it comes into this aspect on which it will be leading up into that exposure of such information. Some are that being that too confident that there's nothing that would happen into them even if they would be trying out to proclaim that they have tons of coins or much money. You wouldn't know on when disaster happens because at the moment that you do share up some information then expect that there would be those who would be trying out to make use of those informations and might that get interested on trying out to lure you in and get your coins. Its hard but its not impossible and we've seen tons of it already. Its better to be careful than say sorry in the end.
