The property can be called a more usual type of investment while bitcoin is something that is new. What is better for investing money, each person must decide for himself. It seems to me it is possible to invest money in both directions if finances permit.
In my opinion, although I am involved in crypto currency, I think investing in property will be safer with less risk than you invest in bitcoin
now there are probably still many people who think that property is the best investment, but some people are now turning to bitcoin.
