Don't sell your assets when they're low. This is a long-term investment. There will be fluctuations and people will take their profits. When the price drops, they'll buy again and the same story will repeat itself.
Buy and wait until more investors come in through news and projects in the currency. Stop losing money in despair. Save up your reserves, because you won't miss them.
I regret selling my bitcoin when it was at 15k because I was afraid of unfounded speculation. The same thing happens with XRP and other currencies with great projects.
