That depends on how you really want to use cryptocurrency in your business. You can decide to create an app that lets people invest in your farm land using cryptocurrency. Saying this because I have seen a company that did that in my country, but the difference would be that they are not accepting cryptocurrencies, we make payment using our debit cards.

But, you can do similar and allow people to invest using cryptocurrency if they wish, and within a fixed period like 6 months or so, they will make some profit. Or maybe you can allow people to purchase farm produce from you by using Bitcoin. I believe there are lots of ideas that you can come up, it all depends on what you really want.
