Maybe profit takers are reason why the price dip so low, don't forget many people bought when the price was down and cheap, and such an opportunity for a good profit present itself, traders will not just hold like other normal investors do, they will always utilise any given opportunity to maximise their profit, it is normal.
Its not only profit takers from holders XRP, its also the pumpers which see opportunity in XRP to be pumped so hard by playing news and rumour.
Thats the reason why XRP price come back to the dip, i think it will going dipper if the support not strong enough.
