Did you really got a cheque from Adbrite? I left them few years back as they are the lowest in paid advertisement. And infolinks is good- you can withdraw the money with payoneer card with them. No need to get cheque . Anyway, If you have cheque and want to withdraw it- go for anybank like: Islami Bank, Brac Bank, DBBL ETC. It's better if you have an account with one of them and cash it in your account.
Go to your bank and deposit the cheque. It would take at least 30 days before you can withdraw the cash. If you don't have a bank account, I suggest you open account at Islami Bank. That would still take you sometime before you can encash the cheque, but that's good enough than nothing.
