I’ve transferred BTC from a kyc change to my {hardware} pockets. The Alternate is aware of that handle belongs to me. Is there any motive to not ship further funds to that very same receiving handle or do I’ve to ship to a brand new handle? I don’t see the advantage of a brand new handle when the KYC already is aware of these addresses belong to me.
In addition to lack of privacy, you open yourself up to certain attacks

It’s “just” a privacy issue. It’s definitely not a security issue.
In general and from privacy perspective it’s rather recommended to always use a new recieving address. All always remember. Once you spend from it, the recepient sees how much funds were on that address. Sometimes (/s) that’s not really wanted.
in the future YES, send to a new address always! even if you haven’t yet spent from that address to compromise it via address reuse.
By separating out the Bitcoin into different addresses, this gives you optionality in the future to spend from each address given the amounts required, either small, medium or large.
think of it like retaining multiple sets of bills in your wallet, like 5, 10s, 20s, hundreds.
with multiple addresses, you have multiple bills.
with one address, you just have one bill getting larger and larger, that will eventually have to be cut up for change when you spend from it. this can be bad for privacy.
but also keep in mind, having multiple smaller bills being combined into one large amount latter on can also be bad for privacy.
But it’s still a best practice to never reuse your address, the outcome is usually better than the alternative.
You sacrifice a little bit of privacy because you’re giving away a little bit of meta data about your bitcoin to the entire world for free.
We might not know that it belongs to you but now we know that 1 address has now received multiple payments that we are 100% certain belong to the same entity.
If you send to a new address each and every time, then there’s no way to know just by looking at the blockchain that the two different payments belong to the same entity.
If you always use a new address for every payment that you receive and send to, we all gain a tiny amount of on-chain privacy.
Also, the exchanges isn’t 100% sure that you actually own that address that you sent to. It’s possible that it belongs to someone else like an exchange or other third party.
Stay private out there.
No address reuse, no exceptions
Fantastic post!
