Lol firstly let's elaborate your list

Land : Has been to a all time low rates many people are selling their land for a loss and some are not getting buyers for their lands so it's literally a waste for many.

House: Maybe it can be profitable but again it will take time to get the right price or you might have to sell it at a loss.

And finally btc the most liquid asset out of the all , it not a investment you can even trade with it other currencies and even earn more money.  You can say btc is high but alts are still undervalued and with this technology in future it can make a huge difference on the economy.
