In staking, you need to think about how much the returns are. The legitimate ones are gonna give you around 10%-15% as the maximum APY. But if you're looking to have more than that, you're taking that much risk.
Aside from that, the lower capital you have and you're thinking of $5-$10 per day, it isn't a simple thing to make because it will require you more capital to achieve that per day profit.
It's worth to mention the coins he used to stake the price wouldn't be same on this day, tomorrow, next 2 days, next week and so on since cryptocurrency price always change in 24 hours depends on demand and supply.
Rather than staking that you're risk too many coins, it's better if he's trading and learn how to understand the market. Though trading doesn't guarantee your will always earn profit, but staking is more like holding, holding altcoins for long time isn't good choice.
