Usually I find it on the smart burn contract that is in the explorer every new token is there, but you have to be careful, because there are also a lot of garbage tokens . only a few diamond coins are hidden. If you want something better, join the channel on the telegram they share - you can follow them, usually already researching before sharing.
Yes, it's true that way, but we have to understand again with a smart burn contract whether it's valid or not, because I've seen several similar applications about altcoin development, and the results are zero from that method.
An easy way to see altcoins going forward is simply by understanding the crypto market assets or the charts that exist in that market.
and its habits, for those who invest at all times pay attention to the development of crypto market assets or their charts.
