Bank offered me money for open account

Salam alaykum

My bank offered me 5 years ago to open a trading account in exchange for €80.

Unconditionally, only to keep the account for 1 year.

I never used the account because the bank had high brokerage fees.

today another bank offered to transfer this account to them.

in exchange for a reimbursement of transaction fees of $200 for 4 months.

with the only condition of having at least $100 in the account at the time of the transfer

are these offers halal or not?

I know that for traditional bank accounts this is not allowed but trading accounts are different

I don’t know if the bank will be remunerated in other ways (sell the data, share loan…)
