Every single bitcoiner should be running a node! Don't trust, verify. If you're not running a node, you're trusting someone else to not lie to you and your not enforcing the rules of Bitcoin that you agree with. A "wallet" is just the key that proves you have ownership, it should really be called a key or signer. The bitcoin doesnt move into a "wallet", it's in the timechain/UTXO (aka blockchain).

But I heard bitcoiner nodes takes a terabyte of storage ! Besides the technical expertise ! And can you run it on phones ? In my mind , most normies are supposed to use lightning wallets ..and only core bitcoiners would indulge in a node ..

Yes you suposed to run a node if you care about your money.
