Bitcoin is a currency like no other. In short it's digital money that solves many of the problems our current currencies suffer from and introduces many other uncertainties we never had to deal with before.I don't recommend putting large sums of money into it as the bubble will inevitably burst in a matter of weeks but nobody knows when exactly. But I do think it's a good idea to get familiar with the system and perhaps buy just a small amount for the experience or to support the growth of the Bitcoin eco-system.
