I don't think so. Those who have invested in solid projects were also investing in the new altcoin, for your information if the fact that new altcoins can also be profitably caused by it has the more chance to grow as long as that was a good coin.
If you find a good altcoin, maybe it will be profitable, but for now I think it's hard to find a new atlcoin that has good potential in the market, most coins now fail in IEO
