In a situation like this, I really agree with your opinion not to take the risk of investing in new coins. For several years it has been very clear that the development of new coins is very great but none of them can last long or even most of them become scams. But we know that, in fact, there are many old coins that can contribute to their holders until now, especially with potential coins that are quite a lot and have been tested so far always giving their best side to their holders. You don't need to analyze anymore, just enter CMC and look for the best ranking, it is certain that it will give positive results.
For long-term investors, old coins such as BTC and ETH are truly worthy choices for a portfolio, and we only need BTC and ETH, or add BNB if investors believe in the Binance ecosystem. I find it difficult to put my faith in most old coins such as EOS, NEO, LTC, BCH...
For investors following the 4-year cycle, waiting for new coins is truly worthwhile so that they can analyze projects and find the most potential tokens. SUI, OP, TON are wise choices, or many other new coins have slight adjustments but are still backed by large funds, they won't easily disappear before the bullrun.
I support investors choosing tokens based on the potential of each token rather than relying on time, but based on statistics, new coins have the potential to bring higher returns in each new cycle.
