Bitcoin has huge potential for making you rich and since its supply is limited it makes it all the more interesting for people to go gaga over it. While it's true that the probability of earning profits through bitcoins is high it is equally possible to lose all your investment also. It is a highly volatile market. Bitcoin trading is no child's play. It isn't a toy that you can just invest in without understanding it first.
Bitcoin makes the world crazy as well as any new invention that has previously done. It changed the whole way of dealing and managing assets of the world that is too familiar and too dependent on the bank. This leaves them having to change their plans to use their money and adapt to it as quickly as possible. Perhaps this makes them confused, but Bitcoin really makes your life easier.
