It feels overwhelming at first, I agree. But you can always dive in deeper.
Want to keep it basic? Just use Lightning which is low-cost, fast, non-technical (unless you want to run a node yourself). It doesn’t cost anything, just download a Lightning wallet and you’re ready to go. It’s free, open and always available. There is only 1 Lightning network and by downloading an app like BlueWallet, MuunWallet, Wallet of Satoshi, Alby etc etc you can be part of it, pay with it and receive money with it.

Want to save for the future? Take real self-custody? Then go for onchain. It’s a bit more difficult to grasp at first, but it’s the safest way to safe your wealth. See this as your savings account
