Ripple is a very promising coin, it is used in the real economy. But the popularity of this altcoin will never exceed bitcoin. In addition, the ripple is a centralized coin, this is a serious drawback.
ripple is indeed a good coin, and is one of the best coins available today. Adri Ripple's development is also very good, however, I think Ripple can't be a bitcoin yet, and there are even many coins that have the same potential as Ripple for now. so, I think bitcoin is still not replaceable by other coins.
