Many experts believe Bitcoin's surge to over $72,000 is just the beginning of its potential growth. Investors may also see this surge as a validation of Bitcoin's potential as a long-term store of value. It is important you do not brag about success. Don’t share how much you have with others. This should be obvious, but there are people that may not be so excited for you. They may tell their friends, and sooner or later someone who you don’t know, who may have the capacity for violence, may decide you are an appetizing target. This is yet another reason to use a multi-sig setup. Even if someone obtained 1 of 3 keys, they cannot steal your Bitcoin. Concurrently, your Bitcoin can be backed up. If you lose your Bitcoin you can literally just magically get it back if you have back up, that's because your Bitcoin is stored on the blockchain. If you have a copy of your "seed phrase" you can regain access to all your Bitcoin no matter which wallet you use. Don't go blabbing your mouth to everyone about your Bitcoin stack.
I will take this as a good enough advice but saying that you are a Bitcoin investor is different to saying that you have 100 Bitcoin in your wallet, everyone is a bitcoin investor in my country but wait till you see the balance, even someone with $20 Bitcoin counted himself as a investor.
It is only those who made mention of their worth that will likely face a problem, its just like having money, everyone has money, but there are levels of money that draw attention, so let's say that everyone has Bitcoin but the amount they have is all that matters.
To tell the truth, I have never seen anyone saying that they have a certain amount of Bitcoin, even $5 in Bitcoin is still Bitcoin, this keeps them safe, but the moment you let the world know that you have 2 BTC upward you are inviting dangers to your door step, like I've said its rare, I've never seen anyone exposing the amount they actually own.
