from what i have gathered about landao as a compony that is into tokenisation of real estate and as a growing company , I believe as a company that wants to increase its threshold in real estate there should be need to enlighten investors of previous successful lands transactions as this will not only make investors to invest with landao but also it will give them the guarantee that the company is actually into real lands and not virtual land.
If what I have read so far is something to go with, this is the first time the project is starting, so I don't think that they have had any previous purchases of lands transactions. They are still building and project from scratch Unless the project was existing the past with another name, which I don't think is the case here. But one thing that potential investors should bear in mind is that, if they project said they are into real land and not virtual lands, I don't think there is any reason to doubt them. Because if they were deal with virtual lands, they would have mentioned it.
