One of my worries is; if people collateralize their land, homes and other real properties they have by taking loans with cryptocurrency as the medium of transaction and with high hopes of increased value in the future. We will not be able to predict what could happen in the future, its driven by the sentiments of market participants.

In the point of viewpoint of a realtor, what if the cryptocurrency payments will experience an extended bear cycle? How will they be able to hedge such risk? How will they account for these losses? How will they able to value the properties with constantly fluctuating prices? Will they allow double mortgages with payments backed by cryptocurrencies? Will they allow renewal of loans? And others.

It can affect the global financial system if the devaluation of cryptocurrencies will happen for a long time especially the banking institutions where they will be forced to write off the loans, unpaid interest allowing them to lose millions of dollars and couldn't pay off other depositors.

Also, the real estate industry where they will not be able to sell the properties at a decent amount of price to cover the costs of development.

In conclusion, if real estate industry will get into cryptos, companies should consider the stability of valuation of the properties and hedging of risks when using it as mode of economic transaction.
