You can send sats to a Bitcoin address, but make sure you send a lot. Bitcoin on chain may require high fees to move again, and if you send too few sats on chain, they can get devoured by the fee. At least 1M sats in a utxo is a safe amount.

What if you sent $10 of Bitcoin to an address and when you go to send it, the fee is $15? That will be a real problem in the future. So if you want to store small amounts like that, it's best to keep it on a lightning wallet like Phoenix or Mutiny until you have enough to send it all in bulk to an on-chain address. Try to see if where you are buying it supports lightning withdrawals.

Possible, yes. But the costs of on chain transactions make it impractical. What are your actual intentions here? What do you plan to eventually DO with the sats? The most important thing you can do is keep control over them, and paying transaction costs to do on chain transactions is a good way of losing control over them.

For long term self custody. Makes sense. But costly. Here's an answer I found on Reddit: ---- LN is a payment layer (offchain) which uses a hub and spoke model and requires an always on and reachable LN node to participate (and BTC locked up) It is not possible to interface with the lightning network with a hardware wallet. the best these vendors can do is get a middleman onboard to provide LN support (essentially, you would transfer your cold storage BTC to the vendor who would transfer it to you via LN for a service fee). ---- I can tell you that the Strike app sees the lightning network and on chain network as parallel services, so any sats you send to a strike wallet you can then transfer on chain to a hardware wallet address. But as I don't have a hardware wallet myself I can't go into details about HOW exactly to do that if it's more complicated than just an address to send to. And you would have to pay the on chain transaction fees so make sure you have enough to make it worth that cost.
