I will give a example:

ICO is bought for 100 BTC (this is $35,000)


48 apartments can be build for $10,000,000. Every apartment will give a average of $2000 per month as rent so that is almost $100,000 per month. After 100 months the whole investment will be paid.

What had HYC to do with this project? Nothing, as $35,000 is low when we have to pay $10,000,000. But with $35,000 HYC will own 0.3% of the apartment block, so meaning every month it will return $100,000 * 0.3%. But return will be paid based on HYC price and this amount will be given to the HYC owners. By having a real mortage schema, it is a coin that should keep his return, every month.
