Bitcoin is young, new, and yes, it is very risky; but it is actually leading us to a more convenient life. With bitcoin, paying with credit cards is now safer. As fraud was very rampant nowadays, bitcoin offers credit card owners freedom from concerns of fraud, identity theft, and those crippling high interest rates. Also, it is easier for someone to transfer money anywhere in the world that cost just a few pennies, and you can send as much value as you want. The best thing about bitcoin is that we can also earn from this. Getting paid by joining signature and bounty campaigns or by trading. With trading, it's quite risky but being knowledgeable, patient and wise i think is the key to really earn a good profit!
