Why isn't the price of XRP increasing drastically?
Because we are all waiting for:
-The launch of RLUSD (they said 'soon' on their Twitter, but what does 'soon' mean for them?)
-January 20 (Trump)
-To verify if it will be used on payment platforms
-To verify if it will be used by large nations for major transfers.
Another factor is that XRP does not use Blockchain technology and proof of work to verify transactions and does not pay validators for this task, so it competes with more classic technologies like BTC and this can move far away from what is now the great heart of the market.
