Why does the total number of coins exceed the number available for sale? What are the other coins for?

The increasingly widespread use of cryptocurrencies will lead to an increase in the value of those currencies that present strong collateral. DomusCoins has all the characteristics to be a protagonist in this market. In any case, the value of DOC will grow at least as much as that of real estate. So you will always be able to sell the DOCs at a higher value after a while.
When you own a real estate property it’s likely that you rent it out and take a profit out of it. DomusCoins rents out the properties on short-term basis to maximize profits. Profits will be shared proportionally with all the DomusCoins’ holders. When you sell a property you do it to make a profit. Again, this happens with DomusCoins: when a property is sold, the profit, in DOCs, is shared with all the DomusCoins’ holders. Even after a sale, the emission value of your DomusCoins will always be guaranteed.

I have long been trying to find the answer to this question. But everywhere they write something in common. Like real estate in Dubai, America and so on, and where exactly - is unknown
