And in my opinion, i am impressed for the facts that bitcoin are,
1.Bitcoin transactions are simple, easy, and cheap. Since the buyers cannot claim their money back after purchase, it gives the sellers an opportunity to ship the product or service to the buyer without any worry of recovery.
2.Bitcoin is portable: With the current major currencies, it is difficult to carry around large amounts of money. Cash amounting to millions is risky to carry for several reasons, which is why Bitcoin investors prefer it to other currencies. With Bitcoin, you can easily carry around a million dollars worth of Bitcoin in a memory card.
3.Bitcoin purchases are discrete. Unless a user voluntarily publishes his Bitcoin transactions, his purchases are never associated with his personal identity, much like cash-only purchases, and cannot be traced back to him. In fact, the anonymous Bitcoin address that is generated for user purchases changes with each transaction.
