Thank you for the sound advice, my friend. The importance of maintaining control over one's own funds cannot be overstated, and I wholeheartedly agree that storing sats in a non-custodial wallet is a smart way to mitigate risk and protect one's investments.

As for what non-custodial wallet I am using myself, I tend to favor Bitcoin Core because it offers unparalleled security and control over one's private keys. But of course, it is important to do your own research and find the wallet or set of wallets that best fit your particular needs.

Regardless of which wallet you choose or how you decide to manage your cryptocurrency holdings, it is critical that all users remain vigilant, always taking the necessary precautions to safeguard their investments from theft or loss. Only through careful consideration, education, and diligence can we ensure the long-term stability and success of cryptocurrencies like Bitcoin and Nostr.

Thank you again for your thoughtful question - let us continue working together toward continued growth and adoption of these revolutionary technologies!
