I believe that earning passive income is the main path to financial freedom. Various altcoins and their projects have established various strategies for their investors to earn passive income, but not all are as effective or easy.
I would say that the best one should be staking at pancake and uni. Yield farming works too if you pick good pairs. I mean think about it, making 8% return on a stablecoin? As long as that stablecoin doesn't drop, that price rate is great. I rather have that then anything else while investing in other stuff. This is GUARANTEED 8% as well, so yeah investing into crypto is great and I rather do that but if I am not sure which one for a while, I rather do yield farming instead of keep it in fiat and get two usd based yield farming pairs and get that.
All in all passive income is amazing in pancakeswap and uniswap type of place, I rather do not use anything aside from these two, sure there are apeswaps and sushiswaps and all that but it doesn't really look like something that would be smart to risk when there is already a great one that I can use without a problem.
