I'd forego the benefit of the doubt, it's most likely going to be used for a scam. They're most likely going to use past transactions as a method to showcase how "trustworthy" they are or something along those lines. There might be some non-damaging ones like the others have said with airdrops and whatnot, but eh, I'd much rather err than give someone access to capabilities to scam others. Seeing as there's a lot of people who has recently seen stuff like this, there might just be an event/airdrop that's going to happen somewhere with a new unknown project though.
That was my first thought too
if so, scammers are smart and are really putting not only effort but money as well it’s quite surprising how far these scammers can go just to gain profit from deceiving people
recently there have been threads buying old eth wallets too.
if this is all about airdrop which the project only send to old eth wallets, how do we know which project is this?
maybe we will not missed this airdrop this time. anyone knew something?
Along with this requirements, some airdrop requires an old address with past activities to avoid airdrop abuser that create multiple account to claim multiple airdrop. You can follow those startup project especially L1 and L2 project that is just doing test net. But airdrop nowadays is guaranteed and requires spending.
on the other hand, this also makes sense
both situations are very plausible however the 2nd situation might be used to justify real scammers
