I really like coins with real assets for backing.

What I don't understand is how can you guarantee a liquidity ratio of 70% of the currency's market value?
The value of the currency on the market can explode anytime and goes up 50% in a day or more. In a one day time you will not be able to purchase new real estates to back up the market value of the coin. Especially since you did not get new money if currency only changes hands on exchange and rises price.
Can you please explain this since I'm probably not getting it correctly?
Thanks
