Most people will want to see the house in person prior to making an offer, and will frequently at the very least look at comparable listings of
sold properties in the area as well.
I think it is somewhat counterintuitive to list your home on bitify as the terms of a contract to purchase real estate are almost always much more involved than "I offer $
x for your house", and usually include a number of disclosures.
If you have not done so already, I would recommend at least consulting with a real estate agent to possibly give you some advice on how to maximize your chances of selling your property at the price you want, and representing you if you feel like that would be beneficial to you.
You can of course conduct business however you wish, however I believe the above will result in the most money in your pocket at the end of the day
