Buy more now?

So this may seem like a no brainer. I have a good bag of XRP and I truly beleive in its long term potential. But ive just managed to free up some extra coin to invest in it. I was watching it at $4 (aus) and hoping for a little dip to $3.70 or so but its only kept climbing this past week. Now it's sitting at $5.30 and has been hovering there the past day or two. Im thinking it's going to hold there until Jan 20th. So I am wondering wether Jan the 20th will catapult its price even higher pending Trumps actions and SEC outcomes. I know that no one here really has the answers but maybe I am hoping for a little wisdom to ignore my buying power at this price and keep considering long term and just slap what i have spare into it at 5 buckaroos. I guess im answering my own question here but do i just buy more now while I can and while it's still (imo) undervalued?
