I think the coins that are undervalued as of the moment especially while we are having a bullish momentum are NEO, DASH, LTC and most especially XRP but I have a strong feeling that these coins will make a breakthrough before this bull run ends.
Any estimation until the bull run ends? Compared with the previous year, seems that we are on the upwave and still more to come, and last year March was the start of the fall for all crypto, synced with the start of the pandemic all over the world. Since than, 1k%+ for a lot of the altcoins in top 100, which means a lot of gains for the holders.
