Now this is what I mean: assuming you sold your piece of landform $20k, you use $10-13k to invest in bitcoin and the remaining $7k to buy another land somewhere at a cheap rate. Surely, with years the value of that land will always appreciate so you still have a land (only that it's at a different location) while you invest in bitcoin stead of using (risking) all the money at ones.
Only the wise ones and knowledgeable ones will reason towards this direction. Some people are selling their properties because of FOMO, they think they will miss out if they did not sell and invest now, not knowing that they need to learn and know how to manage and control their wealth before they can succeed even in the bitcoin investment they are claiming to move to.
Any property like land that appreciates in value deserve to be kept, but lost if this decisions depends on individual thinking and ideology; but if I have a land that is of no use for me for some time, I will sell the land and invest some percentage of the money in Bitcoin and buy at least a smaller land to backup my Bitcoin investment.
