I'll sell the bitcoin I have just for something as important as buying a house and I think investing in real estate will also give you a profit but have a longer time, but it's a good investment too
If only i have that much money, i would also like to invest in real estate properties. Yes it will take much longer, but once it will be matured enough, and you decided to sell that specific investment, it will bring you lots of profits, but nah i also need to invest in real estate for my own benefit and usage not for business.
