[Advantages]

Sharing some info for newbie like me to understand more, bit insight of bitcoin. 

Advantages
Payment freedom - It is possible to send and receive bitcoins anywhere in the world at any time.
No bank holidays. No borders. No bureaucracy. Bitcoin allows its users to be in full control of their money.
Choose your own fees - There is no fee to receive bitcoins, and many wallets let you control how large a fee
to pay when spending. Higher fees can encourage faster confirmation of your transactions. Fees are unrelated
to the amount transferred, so it's possible to send 100,000 bitcoins for the same fee it costs to send 1 bitcoin.
Additionally, merchant processors exist to assist merchants in processing transactions, converting bitcoins to
fiat currency and depositing funds directly into merchants' bank accounts daily. As these services are based on
Bitcoin, they can be offered for much lower fees than with PayPal or credit card networks.
Fewer risks for merchants - Bitcoin transactions are secure, irreversible, and do not contain customers’ sensitive
 or personal information. This protects merchants from losses caused by fraud or fraudulent chargebacks, and
there is no need for PCI compliance. Merchants can easily expand to new markets where either credit cards are
not available or fraud rates are unacceptably high. The net results are lower fees, larger markets, and fewer
administrative costs.
Security and control - Bitcoin users are in full control of their transactions; it is impossible for merchants to force
 unwanted or unnoticed charges as can happen with other payment methods. Bitcoin payments can be made
without personal information tied to the transaction. This offers strong protection against identity theft. Bitcoin
users can also protect their money with backup and encryption.
Transparent and neutral - All information concerning the Bitcoin money supply itself is readily available on the block
 chain for anybody to verify and use in real-time. No individual or organization can control or manipulate the Bitcoin
protocol because it is cryptographically secure. This allows the core of Bitcoin to be trusted for being completely neutral,
 transparent and predictable.

Disadvantages

Degree of acceptance - Many people are still unaware of Bitcoin. Every day, more businesses accept bitcoins because
they want the advantages of doing so, but the list remains small and still needs to grow in order to benefit from network effects.
Volatility - The total value of bitcoins in circulation and the number of businesses using Bitcoin are still very small compared
to what they could be. Therefore, relatively small events, trades, or business activities can significantly affect the price. In theory,
this volatility will decrease as Bitcoin markets and the technology matures. Never before has the world seen a start-up currency,
so it is truly difficult (and exciting) to imagine how it will play out.
Ongoing development - Bitcoin software is still in beta with many incomplete features in active development. New tools,
features, and services are being developed to make Bitcoin more secure and accessible to the masses. Some of these are still not
ready for everyone. Most Bitcoin businesses are new and still offer no insurance. In general, Bitcoin is still in the process of maturing.
