vulnerability to hackers, high fees and not being accepted as a payment form... it would take years before people start accepting bitcoins as one of the accepted form of payment globally
Bitcoin has advantages and there are many disadvantages. One of the biggest issues is trading. Bitcoin has no own banking system, which is a major problem. There is a lot more to be hacking. Many people are betrayed by transactional fraud. Which is sad .I would like to have more secretive information about Bitcoin's superior employees so that no one fall to cheated.
