If they don't mine or produce blocks, why do some people still run their own nodes?
Client diversity is very important: if the vast majority of nodes use the same client, a vulnerability in that client could affect the entire network.
Light clients only download block headers. When they need data for a particular transaction, they request the data and a Merkle proof from a full node.
The old me: place an order first, ask questions later. The new me: understand the rules.
If you're unfamiliar with a product, don't invest heavily right away. It's safer to try it with a small amount first.
