I am not trying to tell anyone to sell their properties to buy Butcoin, I have more lands that's why I am able to sell for Bitcoin, I think it's wrong having a land or two and sell because of Bitcoin, but if you have more, it's going to worth the risk, nothing grows insanely well like bitcoin does.
You have said it all in this little paragraph. The decision to sell your property for bitcoin will depend on the number of properties you have, the importance and the profit potential of the property whether it has future prospects or not.
Land is a profitable property to have, but in some few cases, you can run at a big loss holding on to some properties when you should have sold them off and invested in something better like bitcoins.
Do not hurriedly sell off your land for bitcoins, if it is something you must do, it should be a decision you make on your own and not out of pressure.
Do you mean bitcoin is better than real estate? Real estate at risk and bitcoin without risk? All investments are risky, real estate and gold are considered the safest investments, if they are risky, then bitcoin is even riskier. I am a bitcoin investor, but we need real judgment, I don't like bias for any asset. If you say bitcoin is more profitable than real estate, then I would agree with you. But saying that real estate is riskier than bitcoin is not entirely accurate.
