There are some exchanges that would make direct fiat deposit into your account through a withdrawal process. All depends on your location, amount and fiat which you want to receive though. I would also suggest -only a suggestion, not a recommendation- one of the easier and more straight forward ways is to use localbitcoin where you can sell directly to a local buyer and you can receive payment straight into your account or you can meet locally if it suits you better. Suffice to say, you have be very cautious when using any service like this to make sure you’re not scammed.
