naaaaaa . bitcoin cant replace by any other cryptocurrency . if ever they can replace bitcoin , its ok bitcoin has done to it .
IMO, in future there is a strong chance that Bitcoin will be replaced with a technologically advanced crypto-currency. Bitcoin has a lot of advantages, but at the same time, it is having a few issues as well. In future, if a new crypto-currency is capable of avoiding these issues, then there is a good chance that it will replace Bitcoin.
