I think it's BEAM, SERO, GRIN, QUANT coins. These coins have a very very higher potential for the future. All of these coins price have increased incredibly from their sale price. If you want to invest in altcoins in this year, then don't forget to have a look at these coins. Good luck.
These are quite potential options in this discounted market and I am very fond of new coins in the market so I will consider the coins you have listed. This market has thousands of coins available but to find a good project to invest is really difficult because not all projects are really good to make a profit. I believe that if the market can maintain great stability in the next 3 months, many altcoin will have very high prices compared to the present.
