At what point are you now in your understanding of bitcoin? I would at least.

1. Run your own full node in mainnet.

2. Run a pruned node in testnet for training/education

a. get a basic understanding of how transactions flow.

b. memspool.space good place to track transaction(s)

c. testnet great place to experiment without risk of losing funds.

3. Use a self-hosted bitcoin wallet with cold storage

4. Use no-KYC method for stacking sats.

Think of bitcoin like you do a car. Just learn how to drive it at first, then go deeper into the inner workings of it as time allows.
