Real Estate indeed requires more proficiency compared to crypto. When you invest crypto, you have 1 or 2 choices if you want to on the safe side anyway. (it is either btc or eth). When you invest in Real Estate, there are many stuff you need to be aware of. Which area the property is in, who owns it, how are the neighbors, are there any legal problems with the property, how is the physical condition etc etc There are many questions you need to ask.
And then the tenants are a pain in the butt to deal with too. If you want a peace of mind, invest in crypto. It is invest and forget. Anybody can do that. Real Estate... it is damn troublesome.
Cryptocurrency are very risky due to their high volatility so if any one should consider between investing in cryptocurrency and real estate, except it is Bitcoin that is an asset that one can invest on and have peace of mind but if it involves other cryptocurrency other than Bitcoin then the real estate investment is preferable because even though it has it's own challenges but it is a very lucrative investment that the proceeds are very huge just that it requires a huge amount of money to invest in real estate of which not everyone can be able to acquire a real estate business but for crypto assets like Bitcoins, you can be investing with little amount from time to time and own a huge investment in it.
