for me Bitcoin allows me to hold some saving out of the banking system and the hands of the government.
For me the best in bitcoin is the transactions made on it, it is very convinient to send money, loading your cellphone and paying your bills any where you are. And now the trasaction was too fast than before. Or they can exchange as a real money and you can withdraw any remittances. And tha second is bitcoin is free to all of us. They can used anytime or anywhere. And you can earn without spending a real money. All you have to do is grab the opportunity that you received.
