New projects are generally good for seasoned and experienced traders. They have enough knowledge and experience to evaluate and understand whether a project is good or not because they know what metrics they need to check for it. For newbies, I would recommend they stick with old projects and cryptocurrencies for the safety of their funds.
I agree. The current altcoin scene is evolving in new trends and I doubt its long term sustainability and user base, so it would be risky not to really know that, so I think coins with solid foundations like ETH, SOL, BNB are more reliable and safe. Countless altcoins after their run have failed to recover following bitcoin, it has lost its hype or is no longer relevant, perhaps
I would also add TON to the list you mentioned.
