this also happened to me .. i have a coin that i have left for a long time..but no power to pump it for almost years the price is still stagnating there. Maybe I didn't expect it to come back, I thought it was my failed investment. I will never sell it.. who knows at some point or when the coin could pump even better.. hope but not too hopeful.
You have to update information including liquidity for coins that have been added to the portfolio, many changes occur in projects without us knowing and there are even projects ending in scam, if holding top coins maybe you can check the portfolio because your portfolio balance may have increasing market growth effect.
