Ask yourself a question "What pros and cons of a bitcoin? " and you will know the answer. I can see only two pros:
1. It is anonymous which is makes it excellent for any shade transactions, excellent tool for the criminals
2. It is real, it can not be printed as any other currency.
3. It is reliable and secure
4. It is irreversible
5. The supply and inflation rate are publicly known and unmodifiable.
6. It is fast.
7. The transaction fees are currently significantly less than any other electronic payment method.
8. It can be backed up to protect against loss in a fire, flood, tornado, etc.
9. It is as easy to transport $1 worth as it is to transport $1 million worth.
10. It is easy to hide and to secure against theft
Cons:
1. It is anonymous which leads to many other cons (please feel free to add below)
2. There is no regulation, and therefore no protection from theft.
3. There are no deposits insured by a reliable underwriter.
4. It is still complex for the average user to use and secure.
5. Most of the "wallets" have quirks that the user must adapt to.
6. Lack of current infrastructure significantly limits the ability to use and exchange.
