I don't get a physical part because Bitcoin is digital and does not have physical characteristics. But to maintain its security, I take the precautions needed to keep my coins safe. Hackers or scammers will do anything to steal our coins.
In some point, Bitcoin is also physical if you manage to write the corresponding public/private keys within a piece of paper. The key here is to secure your coins as much as you can against hacks, or physical access (in case you store your coins in a paper wallet). By doing your own research across the web, you'll become knowledgeable on how to properly secure your cryptocurrency funds. Sure, hackers or scammers will devise ways on how to get access to your cryptocurrencies, but it would be up to you to maintain yourself updated about the latest threats.
Personally, I try to read the news everyday related to the latest crypto trends. That way, I maintain myself informed about what are the hacker's latest moves to protect myself against them. By using an up-to-date antivirus and firewall software, a secure operating system like Linux, and verifying hashes when downloading the latest wallet version, you can keep yourself protected against hacks for good. This is even better if you only always use hardware wallets or wallets with keys that had been generated offline to keep hackers away from your funds.
Be aware though, that there's nothing 100% secure in this life, and a small mistake from you, could cost you dearly.
