Top altcoins are the most profitable coins if you were bought during the ICO or after the exchange listed. 100x, 200x or 300x pumped the altcoins price but any new coins couldn't make it. We have some altcoins history that were launched during the last quarter of last year. Most cryptocurrency can't be predicted for the next bullrun, but the top coins are safe.
yes that's proven and on this situation they're are so easy to see because market is red.. Indeed if you subscribe to coinmarketcap you will he notified if there's a new projects listed.. Very worth it for me in my personal opinion because new projects always make good improvement after listing and etc, but not for long term only short-term because you know it's quite skeptical and most of them didn't last afterwards, that's what i noticed after how many months riding new projects trend. Lol
