Legit question, especially these days where bear market took place for about a full year now. At this moment land is considered as something more secure and it is an axiom. On contrary Cryptospace is curently going thorough rough times and nobody knows when and what will encourage investors to become part of new economy and bring new value to the ecosystem. Furthermore it depends on how will you treat your land or  bitcoin couse having a  capital and do nothing with it is just  stupid. 

On the other hand the  question is uncomplete as you didn't mentioned any specific relations nor thoughts which makes really hard to make a logical statemant. But if you ask me if i would have some small plot or  bitcoin i would prefeer having bitcoin(assuming that we have equivalent price ratio). The reason for it is that it is  easier to use and maneuver BTC around rather than process the land, at least i see it that way. What are your thoughts?
