I can not sell my land or property to buy bitcoin. It will make me look like I am risking too much and which could affect me. My property remain my property and the land will continue to increase in value too. This is what I will think and I will not sell my land. Sometimes it is not about the profit, but diversification.
I respect your opinion of not selling your land to buy Bitcoin. But this is different is OP has an abundance of land from what he said. It was a good form for him to sell a portion of his land to invest in Bitcoin. Things could go south we know but isn't that what an investment is? He invested what he can afford to lose.
You talked about diversification. Selling a part of his land to invest in something is diversification. Now he has assets in land and Bitcoin.
