I find this question confusing. Staking is a process where you need certain amount of tokens to earn from its timely maturation which classify also as type of investment.
Staking is a form of investing, you'd need to specify what form of investment to compare it with.
I mean, by investing, you place your currencies in investment sites that give you a percentage of daily or monthly percentage profits. I see that staking is very similar to these sites. Also, as you know, there are risks in this type of investment, and my question is what is the difference between staking and such sites, as well as whether there is such a risk.
