Random Micro Deposits into unused 2017 Native Segwit BTC Address

Okay, so hear me out because I’m extremely confused and this requires all details to get to the bottom. I’ve been in web3 since 2014 and can track down everything on-chain and have never struggled to figure out a problem. I’ve never been hacked and I’m very very familiar with the blockchain and its inherent operations; specializing in BTC and ETH specifically.

I bought my first ledger in late 2016 and used it mainly for bitcoin and had some ETH/XRP transactions as well. I stopped using that ledger around 2018 and since have purchased 3/4 new ledgers.

However, as you all know, you secure your ledger by writing down a 24 word mnemonic that can be used to restore all wallets associated to the ledger (in the case your ledger gets destroyed or whatever else may happen).

Well, I no longer have that physical 2016 ledger but I had the 24-word mnemonic written down on a ledger sheet from 2016 and I decided to use it to restore one of my more recent ledgers (which I recently decommissioned) to explore any airdrops on my ETH accounts (one can hope).

To my surprise, this is as of today, as I was adding the wallets back to Ledger Live, I notice ~280$USD in Bitcoin on a “Native Segwit” wallet.

Now, similar to the rest of you, I thought, this must be some old bitcoin dust I left around in this wallet because it probably wasn’t worth enough in 2016 to move… right?… WRONG.

Turns out, since December of 2023 this wallet has been receiving random amounts of BTC spanning from $6 at a time to $120 at a single time every 2-3 days. It accumulated from December 28 2023 to June 13 2024 (~5.5 months) roughly 2,400$ USD in BTC…

THIS NEXT PART IS WHERE I GET COMPLETELY LOST AND CLUELESS…

On June 13 someone transfers the sum of 2400$ USD to another wallet… I did not conduct that transaction…

I was extremely lost at this point. I came to find out about this wallet today, earlier. Since the last transfer out of $2400 it built roughly ~280$ USD and so I transferred it out to see if it stops this random deposit occurrence.

Now, I need help figuring out how this is possible? Seriously, it’s just haunting me and I need help.

Some key notes: - Ledger was purchased from their official store - Mnemonic was stored in a safe only I have access too - I did not share this ledger or ever have this ledger compromised - I Last used the ledger associated to this mnemonic in 2018 and all its other wallets reflect this in their transaction history - I didn’t know of any of these deposits or the $2400 USD withdrawal until today

The address that has been getting all these incoming deposits and has conducted the withdrawal is part of my native Segwit wallet. The specific address at question is;
