Investment sites involve a lot of risk and you hardly know the truth about where your money is going for that are being used to pay you monthly. Staking is less resource-intensive alternative to mining. It is less risky but the profit might be less than what you are getting from investment site. Also profit from staking varies depending on the amount of coin you are staking and the coin itself. For me, I prefer staking over the other
That's right, I recently started using a stake and found it much better than investing in other types that you don't know exactly its work and may be scam, at least in the stake you're dealing with a coin that you trust and know well.
