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.
Indirectly conditions like this actually become flexible because everyone has clear opinions and arguments and of course the two arguments between those who agree with selling or disagree are not all wrong because indeed everyone has their own opinion about it.
If we really have the same opportunity, in the end, the choice is in our hands, because regardless of selling property or taking other approaches, such as buying little by little bitcoins for investment and waiting for the lowest price to buy more, everything can be justified. It's just that this choice has to be seen from several perspectives where it's like what the OP said, he's selling because he has a lot of properties so it's not wrong to sell and make it into bitcoin but it's definitely not recommended for someone who only has one property and all of this here by selling their assets and being in bitcoin.
Even if that action is not a mistake either, of course we have to think about all conditions because this is an investment and of course when talking about investment, of course it has a short period of time so you don't have to risk everything and you don't think about tomorrow.
