What do you expect from the centralised currency like XRP which is being run on the blockchain technology. It's like combination of the government fiat currency and the block chain technology. They will keep it fiat only but the only thing that will different is, the platform on which they are carrying their operations. That's as simple as it looks like to understand. Never rush your investment into currency like XRP because they will keep its supply always high and they will keep manipulation going on so that they won't need to payback more than what is required.
