Most coins experience price drop after the alt season early 2018. Now its hard to reach their last ath again and stellar is among of these alts who has potential but the price is not showing major growth. Its a good coin indeed but just like other top coins it takes time before we can see these alts soaring high again. Nevertheless if you believe in stellar coin just buy and hold.
as long as they still have a hefty market, I think the potential we can still expect for stellar coins. but indeed that time will not come quickly. even today some traders may use XLM to withdraw their money from one exchange to another exchange because the costs are fairly cheap.
