Bitcoin really does have many advantages, just look at what btc achieved now. Its users have freedom and have a full control over their funds, and as it is a decentralized, no one can manipulate it and users would not worry on what will happen on their money, unless they've become careless and indiscreet resulting for them to get scammed.
For those in business, bitcoin is also a huge advantage. Business transactions in btc cannot be reversed and also logged in the block chain which can be seen by public. These protects the user in fraudulent business transactions and avoid loss of money.
