I like about bitcoin is it is decentralized currency, it is very safe to use, value of the btc changes fast so that we get the benefit at the maximum level than the gold or other parts of investment. As well as it is easily transferable to others.
Decentralization and price volatility are the key features in bitcoins that makes it unique from other currencies and other forms of investments as decentralized allows you to hide your identity and price volatility will help you in making quick profits if you take right decision at a right time and the other key factor in bitcoin is that it gives you an extra source of income which can improve your standard of living.
