Both are good investment, if you have both then you're lucky.
It is true that land as a property is such a good investment, however, the tax you're going to pay per month or per year is also a pain in the ass if you don't put anything in your land, like raising livestock on it or plants fruits and vegetables to generate more profits. Here in my country, land that are near the roads pitch much higher prices than those who are in a very high places like in farms near the forest.
While Bitcoin, if you bought some and hold for long term, it is all about waiting game until you hit the price where you're contented about selling it, no hassle at all. Though each of them has their own advantages, so either of them is a good investment in short.
I see people often complain about land taxes, maintenance costs...then compare it to investing in bitcoin and think that investing in bitcoin is better. But everything has its price, we pay real estate taxes but in return we will be protected by the law if a dispute occurs, they will ensure the safety of our property. Meanwhile, investing in bitcoin will not cost anything, but in case our bitcoins are stolen or hacked, there will be no one to protect us. Not to mention the price of bitcoin is very volatile and what will happen if the price of bitcoin continuously drops? Meanwhile, with real estate you can create passive income from it.
Each asset has advantages and disadvantages, depending on each person's needs and choices. Don't just because we are bitcoin investors, we can say bad things about the remaining investments. Real estate is not only an asset worth investing in, but it is also an essential need that every person needs, we should not deny that fact.
