Can you analyze to what sort of addresses did you receive that dust? Was that the addresses that you used to withdraw from some exchanges? If so, can you tell from which exchanges? Or was it some other services? Or maybe addresses that were never used (but how it can even possibly happen?)? Maybe we can get some idea who is behind this dusting if we try to start tracking them.
I'll try analizing them ASAP, although I will not share them due to privacy reasons.
They are not addresses that I used on exchanges. In fact, I do not remember using any of my addresses on exchanges and I believe I have not used them for services either. Will try tracking the dust addresses down but I don't know if I'll get to any results.
Many modern wallet (for bicoin for sure, I don't know anything about shitcoins) have a "do not spend" feature you can tag given UTXO with.
So tagging in this way your dust prevents you doing stupid things with that.
I will have to look into that, I've never seen this option on my Ledger though. Thanks for the suggestion, although I think I've even spent some of the UTXOs already..
