go to coinmarketcap or any other chart providing services, your exchange included and go to Ripple page and then continue to zoom out until you see the cycles!
the explanation is very simple,
what is pumped needs to be dumped. Ripple was worth about 700-900 satoshi and when the pump time arrived for all the altcoins it went up to 3000+ satoshi and now it is coming down as everyone exits slowly and then others who bought on top and were bag holding give up on profit and sell at a loss.
and it is happening to all the altcoins and will continue to happen until they are back at normal low price levels.
