Hello again! Is it possible to solve this now somehow? its been almost 3 years

Wow, that is a significant amount given that ETH price has appreciated over time
I understand where they are coming from. The fact that that ETH has stayed in that wallet for all those months without moving means access to private keys to the addresses is near to impossible for security purposes
Maybe you could try pushing them to adopt the BSC network as well. ETH network fees ares still so high anyway.
I remember my deposit to Stake.com where I forgot to include a tag for my deposit, but Stake.com managed to resolve it for me, although it was on a different network or blockchain in my case. When it comes to tokens like this being deposited, it's really hard to recover them. It's better if it's the actual coin because it can still automatically deposit into your account. From what I know, your address for BNB and ETH is the same, like on Stake.com, so even if you send it to the wrong network, it will still be credited to your casino wallet.
I think it's been quite a while since we all advised this player to contact the casino's customer support and ask them to solve the problem once again.
The
BTC bull run has turned his ETH into a very significant amount, which is certainly too much of a shame to lose. And of course it's worth continuing to insist on returning this large amount.
But, however, maybe he has already solved this issue? He just hasn't written anything here?
