For me, my favorite token in altcoins is EXRN token from EXRP Network because having this token is very exciting especially when you participate in their airdrop, they gives 10 million tokens each for 7000 users participants. This token is a chain because if you hold your EXRN token for 3 months you can earn another token also from EXRP Network I think. EXRT token is the reward for EXRN token holders.
