Investments have risks but crypto is riskier than real estate, and real estate can really last a long time if it's being maintained well. Also, if you have like a land, you can build a house or something that you can use for leasing which is a good passive income. You can earn monthly income with this and at the same time, the property or the land will appreciate over time esp if it's in a great location. HOWEVER, with a capital of less than $2.5k, you can only purchase a small area of land with limited location since the prices of land are increasing. You definitely need more than that capital if you want a decent portion of land and area.

But if it's really the only budget you can allot, then go for crypto. There's no problem with crypto and Bitcoin as long as you're knowledgeable and you know what you're dealing with. Unlike with real estate, you kinda need to monitor more often how's the market doing. So if you have limited budget but have time (tho it won't really consume you much time of your day), crypto can be your best option. If you really want to invest in crypto, you need to study and what to do and what to avoid since it's a lot riskier and very volatile.
