My most important question: Which is better, staking or investing?
It all depends on what kind of profit you want to make. If your choice falls on stacking, then you will receive a guaranteed but relatively small income. If we consider the investment-then I personally bought a pancake on February 5 and since then my balance has increased significantly, which can not be said pro staking. So my answer is to choose what suits you best.
That is very important! knowing the type of investment to place your money.
You can define that by your own assessment, Staking gives you extra while holding the coin, there's certain amount of shared profits coming from the staking feature of the asset, while with investing alone, you are just holding and waiting for the growth in value of your assets, straigh forward. Learn staking and find the suitable project that will allow you to gain decent profits.
