Yes, right now is the best time to buy Alt, because prices are still cheap, like Cardano, Stellar is the best to invest now, I am sure that in the future prices will continue to increase.
Agree with you mate, this is the best time to buy alts because crypto market is now going good and it seems that bull run is not far to come and while alts price are still down therefore buying alts now will give us more profit in the near future.
Stellar is something that i look for now. Since it is on top 10 coinmarketcap coin (when i post this, i see Stellar is on number 10), i think there are a lot of possibility that Stellar / Lumens to increased in future and worth to invest.
