I've never had the opportunity to hold any Bitcoin, but if I don't get it wrong from what I've learned here, your private key or seed phrase is what secures your bitcoin, which can easily be hacked by fraudsters when using centralized exchanges to keep your bitcoin, which is the reason they keep emphasising that we shouldn't store our bitcoin in exchanges. A digital asset is bitcoin, so remember that there are scammers involved in anything related to cash This is why there are so many talented fraudsters on the internet

IMO it is good we store our bitcoin in a non-custodial wallet, as this will ensure its safety. But remember that even when using a non-custodial wallet, you still own your private key, therefore misplacing your private key it will permanently prevent you from accessing your bitcoin.
