At this point of time, Bitcoin investment looks more profitable to me than real-estate and this is because i feel that property is not the thing whose valuation will increase overnight and you got to wait for a long long time but being a risk-taker, I would prefer to invest in BTCs for the long term in order to get a better payback. Bitcoin is starting to rule again and the levels of profit it can give excites me to the core.
If bitcoin grows, it grows more than value of properties. If it falls, it falls much more than property ever would. So it really depends. Main thing is to diversify your protfolio the right way
