Based on the estimation of having earned 9.5% annual profit, that's a realistic result even though the interest is higher than the bank and if you use $ 1k then the profit is not much but the profit is guaranteed. At least you prepare $10k funds then it will get $950 in a year.
The guaranteed profit is a passive profit with a certain amount of capital and I think it's also not bad to do as long as that amount of capital is not used in other jobs because some people when they have that much capital there must be a new job that they will do wake up if he has unusual abilities or abilities that are more than other people in general.
