stolen BTC from electrum in 2018 accumulated in this adress

[franky1]

its not "some hacker" nor "some whale"

its one of bitfinex's hotwallet addresses it uses to perform withdrawals for many users

in short many many many taints ago the hacker moved hacked coins around and it ended up in bitfinex.. either directly from the hacker depositing into bitfinex or the hacker moving funds between users using other services during the 5 years, and its then random innocent recipient users of that taint that then used bitfinex.. either way, that taint is now sat in a bitfinex hotwallet.

it might be worth the victim(s) that has taint now moved to that address to contact bitfinex. show bitfinex their address they lost funds off of from years ago to show the taint path to bitfinex.
probably worth signing a message with that old key to prove you did have control of funds pre-theft

 and then have bitfinex do an investigation on the history of the utxo spends backwards from todays claim back to victims claim.  to see which user deposited those funds in the middle.

then if other victims of same scam come forward and bitfinex sees a pattern of the same user depositing same funds into bitfinex then bitfinex can report that user..

bitfinex obviously wont just 'out' the depositor publicly, because it might be just be some random guy that accidentality received some tainted coins between 2018-2023

however if alot of victims funds result in going to the same user. then thats less of a random act/random coincidence. to which they can report such a user

edit:
quick search
it seems alot of the electrum phish scam of 2018 has been moving through bitfinex several times and ended up in bitfinexes hotwallet address
even as early as 2019 https://twitter.com/JohnCon54897907/status/1111279898260312066
and it seems again this month.

so it seems too coincidental to be just a random fluke. so bitfinex could do some investigating into this

The address belongs to Bitfinex and has been confirmed by many reputed members of the forum. I also check the address and found many transactions were happening few seconds ago. If it was an address that belonged to hackers group then the address should already be dead until they decided to move the funds from it. But, the scenario is different with this address there funds are constantly moving without any fear from governments and other authorities and that clearly shows that the address is transparent and has no fear from any authorities.

I would recommend you to do your research thoroughly before coming up with a conclusion, and even if the hackers used that hot wallet for moving the funds then still it's not the fault of the exchange because they weren't speculating each transaction done by the users, and they never freeze the withdrawals. By the way, hackers can use fake KYC data and that's why it doesn't make much sense to go behind the one whose KYC information was given during account creation. Those hackers might be so smart to person such malicious action and if they really moved the funds to the wallet then they did that intentionally.
