Everyone including newbies are busy with old altcoins. And it is always advised to ingore new altcoin! But if none of us don't invest in new altcoins, then how will altcoins successful without any investors? Thus all new altcoins will be flopped???
Whatever new altcoins are risky what is known to all but what sign should be noticed before investing altcoins?
I think no one said to ignore new altcoins? They were just warned since newer altcoins have higher risk ratio in comparison to old and well-reputable altcoins. New investors should build up their portfolio and the best way to do that imo is to start with well-trusted coins, and then deviate from there slowly since you'd have a passive way of being able to maintain your money.
While thrusting yourself into the newer altcoin market could bring in a lot of profits if done well, newbies don't know how to do it in the first place. It wouldn't be any different from gambling if they just entered and invested in any altcoin they'd see that would look like would grow, especially if you consider how a LOT of new altcoins are just scams, or will end up to be scams.
