Trying to find exchange using address for access to old forgotten balance

[elpretentio]

I have a friend who I'm assisting with this... they have a balance of 50,000 DOGE on an old exchange they purchased in 2018, but they can't remember which exchange it was.

I've ran through about 20 different exchanges using 'forgot password' to see if anything comes up, but no luck with that so far.

What I was able to find though is this exchange address which is where the BTC was sent in exchange for the DOGE:

1EEqRvnS7XqMoXDcaGL7bLS3hzZi1qUZm1

this is the transaction hash transfer that took place during the swap:

and this is their personal address that sits on the exchange:
https://blockchair.com/bitcoin/address/3BViGbeJaEYw9AUWY9CCYNCGX9QmPVpLBT

There are only two transactions for that user address. One sending BTC to the account on January 13th, 2018. And another transation on February 5th, 2018 which is presumably the swap from BTC to DOGE.

Aside from enterprise services like Chainalysis, is there any tooling available for individuals like myself just looking to cross-reference this address with the exchange it might belong to?

The exchange I traced it to is HitBTC.

If you are referring to doge, this supposed to be on altcoins board. But that address on your post, which I quote below is a bitcoin valid address.

Ok, thank you. May I ask how you traced it to HitBTC?

I use wallet explorer for it.

https://www.walletexplorer.com/

You will see a space at the top of the site, paste the address there and click on search. You will see some transactions there which are inputs are from HitBTC, if you click on some, you will see that they are used for consolidation to the address that you posted above.

Example is this transaction: https://www.walletexplorer.com/txid/007c83ff0da350c5e4f77005966cebbb5ff63163e490d211b24c20ee9382c965

You can see that the sender is HitBTC. It is used to consolidate their high input. Which means HitBTC is also the owner of the receiver address.

Thanks very much for your help.
