Bitcoin was supposed to be a currency, where a person can send any amount of Bitcoins to any other person in any part of the world within 10 mins and with lowest possible fees. But now, due to a major increase in Bitcoins popularity, the time taken for completeing a transaction has increased and is taking more time than 10 mins. In some cases upto 2 hours and in some extreme cases, Bitcoin was not even transferred. Also the fees is rising day by day. All of this is not for which Bitcoin was developed. As a result, if further actions are not taken up by Bitcoin development team, Bitcoin may start to loose its value( which will probably not happen).
