Yes to both.

Mining gives you nonkyc sats but at an upfront cost of the miner plus ongoing electricity costs. Plus it helps secure the network and you can leverage the waste heat in the winter to supplement your heating costs. If you're trying to mine for profit you'll need low cost energy and a top of the line miner.

Buying sats is simple and you can still get nonkyc. It's much faster to stack by buying.

I think every pleb shld stack with dca and then mine some on the side.
