Coinbase delisted XXXX. 
I am XXXX retired and paid {$5000.00} and today it would be worth about {$650.00} but it got delisted and now I am told it is lost on the blockchain and that it is worthless. I want someone to find it and convert it to XXXX. It should never be worth nothing. This feels like a scam!!! 

Back on XX/XX/2023 I sent XXXX XXXX from Coinbase to my friends wallet registered with XXXX. He has been trying to find out from XXXX why he did not receive it. 
Coinbase responds with Thanks for getting in touch regarding your recent transaction. Im happy to provide you with some information that will help you to locate the funds you sent. 

After reviewing your account, I can see the funds have been successfully sent out of your Coinbase account. You can verify this on the block explorer, which is a record of all crypto transactions : XXXX If youre having trouble locating the funds, here are some details to check using the link above : - Ensure you sent funds to the correct address- Ensure you sent funds on the correct network- Ensure you, or the person you sent to, are able to access the wallet where the funds were sent If you sent funds to the wrong address, you will need to contact the receiving party and ask for their cooperation in returning the funds. If you do not know the owner of the address, then there are no other available actions that can be taken to retrieve those funds due to the irreversible nature of cryptocurrency transactions. 

If you are having trouble locating funds sent to a site outside of Coinbase, I recommend reaching out to the support team of that site so they can help you to gain access to the account and locate the funds.

XXXX Please note that XXXX has undergone a major upgrade to XXXX XXXXXXXX, so it was paused. Please check their social media for more info. We know that XXXX XXXX has lost its value and can no longer be credited to our user account from XXXX of this year due to this upgrade.

XXXX Thank you for your patience. We have looked into your matter : XXXX. It seems that the funds were sent from CoinBase in mid-summer. 

XXXX. XXXX XXXX tokens were disabled on the XXXX of XXXX and replaced by the XXXX  XXXX token. Most exchanges, as did we, have done this replacement automatically. CoinBaseXXXX, from what we gathered - didn't : " Do you own XXXX coins on Coinbase as a cryptocurrency investor? If so, you might want to pay close attention to the latest information about XXXX Games ' planned token upgrade. On XX/XX/XXXX, the blockchain gaming startup will send current holders an updated version of its native token, XXXX XXXX, through an airdrop. But there's a catch : the biggest cryptocurrency exchange, Coinbase, has said it won't accept the upgrade and will stop trading the current token ( XXXX XXXX ) on XX/XX/XXXX. '' https : XXXX XXXX. After the XXXX of XXXX, the old token XXXX XXXXXXXX is useless and discredited. This means that even if you've sent the XXXX XXXX tokens to the XXXX wallet, we can no longer receive them, as they are delisted and disabled. They can not be converted to the XXXX XXXX tokens either, as we are not responsible for the switch. This is done on the blockchain level. 
That being said, the funds sent three months after this replacement are without any value or capacity to be received. Hence, they are gone, unfortunately. 
Again, we would like to emphasise that we do not have any capability to impact the blockchain level ; therefore, there is nothing we can do. 

Kind regards, XXXX XXXX XX/XX/2023 I still can not get my lost XXXX back. 
Can someone tell me what I should do? 

Should I file a complaint against Coinbase and XXXX?
