Crypto tax for Gambling

Hi Everyone,

I am based in the UK where Gambling is not taxed, Hence, according to Koinly’s guides - I have uploaded the CSV of my deposits and withdrawals (WIth labels as Deposits and Withdrawals respectively), While all of my bet winnings and losses as Realised P &L.

However, how should I treat bonuses / rakebacks given to me by the Casino? Would the safest option be to tag these as deposits?

Thank you for the help!
