over time will these transactions clear themselves and not be traceable months later? like is the data gone after a time? or will LE be able to look back months and years later to see where they came from?
i'm not going to do this again obviously but do i need to create a new evo and delete my old wallets or can i just start using a new lcb account anom and be fine with my current evo and still use personal wallets for normal stuff?
hope question makes sense
It is good OPSEC to generate a new, unique wallet for every inbound deposit. Unless you are doing something like a public "tip" address that needs to stay the same, there is never a good reason to ever re-use a deposit address.
If you have an Electrum or other local wallet, there is never a reason to hang on to an address that is in any way compromised. If you are really concerned, send the money through a tumbler to a new wallet, but realistically that's probably not necessary, or worth the 1-3% fee you'd pay.
