What are the new crypto coins?

Could you elaborate on the emerging trend of new cryptocurrency coins? I've noticed a surge in the number of digital assets entering the market, and I'm curious to understand the driving factors behind this trend. Are these new coins merely speculative investments or do they possess genuine value and utility? What sets them apart from established cryptos like Bitcoin and Ethereum? Additionally, what are the risks involved in investing in these new coins, and how can investors ensure they are making informed decisions? I'd appreciate your insights on this evolving aspect of the cryptocurrency landscape.
