The whole point of cryptocurrencies is the decentralization part. And ripple doesn't even has that. Why even use the blockchain technology just use the traditional database and be done with it. Plus to add to it, most of the supply of the coin is locked and controlled by its creators.
The fact is that Ripple generally raise doubts about its profitability and prospects. Many people invest in this coin because a good pr-campaign was conducted and many are hoping for a good salary. But basically the whole situation can develop differently.
