Hi all,

I have a bunch of old wallet files in my laptop that I have stored during the years and many testings of various cryptocurrencies.

I have been playing today to check their balance and see if I have any hidden treasure chest (I don't think that's the case).

So far the only positive balance was found in one of the "sending addresses" in Bitcoin Core but if I understand correctly, this is not an address I own but an address I sent money to, correct?

Also, I have another wallet file that I tried to load in Bitcoin Core but was rejected. It might be a wallet of another cryptocurrency (maybe Dogecoin??). How can I check this?
