I want to know what country you're from OP because I want to move there, just 2.5k USD to invest in real estate? That's either an absurd amount or the property that you're buying is in the middle of nowhere so in your case, you're probably better off with crypto investment but not just any crypto, make sure you invest in bitcoin but invest what you can afford to lose. In a broad sense, if you think about which one's more dependent, it's usually which one's got the most security and stability and crypto doesn't have that since it's a volatile investment so I'd say that real estate is more dependable, you know that the price of that property is going to grow.
