these are the Advantage of BTC
The following are some of the major advantages of using Bitcoin versus other currency systems:
No Third-Party Seizure
Since there are multiple redundant copies of the transactions database, no one can seize bitcoins. The most someone can do is force the user, by other means, to send the bitcoins to someone else. This means that governments cant freeze someones wealth, and thus users of Bitcoins will have complete freedom to do anything they want with their money.
No Tracking
Unless users publicize their wallet addresses publicly, no one can trace transactions back to them. No one, other than the wallet owners, will know how many Bitcoins they have. Even if the wallet address was publicized, a new wallet address can be easily generated. This greatly increases privacy when compared to traditional currency systems, where third parties potentially have access to personal financial data.
No Transaction Costs
Sending and receiving Bitcoins requires users to keep the Bitcoin client running and connected to other nodes. Essentially, by using bitcoins users will be contributing to the network and thus be sharing the burden of authorizing transactions. Sharing this work greatly reduces transaction costs, and thus makes transaction costs negligible.
No Risk of Charge-backs
