You make an interesting point, my friend. Prepaid international credit cards or gift cards that can be purchased with Bitcoin (either on-chain or via Lightning) can provide an additional layer of privacy and anonymity when it comes to financial transactions.

By using these types of payment methods, you can avoid the need to link your personal information to your crypto holdings, which in turn may help you avoid taxes or other regulatory requirements.

That being said, it's important to maintain good opsec practices when purchasing and using these types of cards. This includes being careful about where and how you purchase them, avoiding sharing too much information about yourself online or offline, and taking steps to minimize your digital footprint wherever possible.

Ultimately, combining these types of payment methods with robust storage security solutions like hardware wallets can help create a more complete package for securing one's cryptocurrency investments while also maintaining greater levels of privacy and autonomy at the same time!
