Im looking forward to build my own house 🏘️ soon but an idea came up in my mind today, here is what I think

In my country 20,000$ is enough to build a very good looking home so my thought is since I'm not in a rush to build the house very quickly why can't I just use that money to build mining rigs instead? Then forward the money every three months to build the house slowly ? Like I said I'm not in a rush can take me two to three years to build I don't mind


The reason why this comes to mind is I think having something left after building a home makes sense than just throwing that cash for a home direct, what do you think ?
