Property is the best offline investment I know, if I have a few hundred bitcoin, I want to buy some pretty strategic houses, then rent it out, after a few years later I resell it, and it must be worth much higher when I buy
I strongly agree that property(most especially land properties) is one of the best to invest your bitcoins if it reaches your budget. The prices of lands increases as time passes by and can easily be sold to those business tycoons and managers that were interested or searching on a good site to place their establishments. From here you can gain advantage to set your price and earn much better and in that way you can say that you didn't regret investing bitcoins.
