In terms of having an investment in the real world, a house and lot is a good choice because house can serve as a shelter and land will decrease it's value through time. Other investments is jewelry like gold and other gems because as the de!And increases it will become rare. When in terms in digital I will put my money on BTC.
Some things are off and I want to clear it out. Houses
increase value over time but not all of them. It still depends on the location of your house. Some people like living in the provinces but would it be exactly the province where your house is? The houses in the city surely increase its value over time when the city is still relevant. There are times when a city is outgrown by some other near cities.
Minerals, rare stones, gold, etc. they get demand over time because of their use. But it's not demand that makes it rare. Those things are already rare and that makes it have a value. Supposed that you can pick gold stones in the streets, gold wouldn't have as much value.
