I use strike or cash app to make my purchases. The apps also have lightning compatibility (lightning is a second layer for faster transactions.)

I suggest reading The Bitcoin Standard and Broken Money.

It's not just about making money, it's going to take learning about what real money is and why bitcoin fits that bill. You won't want to trade it back to dollars once you understand where we are going.

You won't have to trade bitcoin for "money" (paper federal debt notes, printed infinitum) once you grasp the above concepts.

Don't be discouraged if it doesn't click immediately, you've been conditioned to think your money is the real deal, when in fact it's built like a house of cards.
