If you are talking about mining cryptocurrencies on your own device, the best options would be Ravencoin (RVN), Vertcoin (VTC), and Monero (XMR). However, since mining is no longer a hot topic, do not expect to find much interest in these coins; the current trend is memecoins and investments that bump within less than 24 hours.
I guess mining lost its spark, due to shrinking profitability, since big factors on that is the electricity cost goes up and that eats a lot in their operation. There are also other factor affects it and this is the reason many people shift their interest on something they can easy to handle.
Many gamble in memecoin, but this is actually another not reliable investment.
