Staking cake is a good way to generate passive income, besides cake, bnb, cardano (there are) staking can also be done. but maybe now there is a way to play games using coin axs can also generate income besides we also get additional entertainment by playing games
Its good to find something alike that have potential than to just join in a hype that may end any moment since the hype is already there. While its good to join in it we must know how to monitor still since the market is too volatile and dont put all in it , haveother investment in other coins or properties.
Yes staking the coin is one of the most popular option to earn passive income in the crypto currency world. Cake offers a very good ROI so it is a very good option. But I recommend staking in multiple coins as there are many different options for you like bnb , cardano as you said.
