Bitcoin is the only asset and form of money you should consider traveling with in large quantities as a digital nomad. Cash can be easily stolen or raise questions at airport security. As for gold, do not even get me started. Storing your wealth in banks or stocks is not the way of a sovereign citizen. These are centralized systems controlled by governments and institutions that decide who can access your money or how much it is worth.
Bitcoin is a decentralized digital asset that you fully control. The security and value of your Bitcoin is in your hands alone. Use a cold wallet to store your funds offline, safe from online hacks and surveillance. This way your wealth remains truly yours, not held hostage by banks or governments.
If you want to understand this revolution, I recommend reading books such as The Bitcoin Standard and Broken Money. They offer insights into what Bitcoin means for personal freedom and monetary sovereignty. Learning about Bitcoin is a crucial step toward taking full control of your financial life as a modern digital nomad.
