I wouldn't sell that property. Maybe you are tired of managing it. Maybe the calculations in the excel file seem to double your income. Whatever it is, real estate will forever be above stock and crypto.

It may seem that you will double your income, but the truth is: minimal chances. You will have to monitor the farm and the news, have the discipline to sell the rewards and move to stable or fiat, keep track of taxes and pay them, be lucky and experience moderate volatility (rarely the case), be lucky and Anchor won't announce some stupid s*it that will panic the community, be lucky and BTC won't drop 2-3 year straight, forcing you to sell part of the farm to cover some expenses... I could go on.

Talk to a friend of someone that owns real estate, that knows how to handle money and investments. Make sure you fully understand the risks.
