The highest in Canada that I've found is 2.8% interest, compounded annually where the interest is calculated daily. I have $2000, and the initial amount and the interest earned is guaranteed by a governing body.
Though, I spoke to some people and they suggested since I don't have much, ~10K in total, the interest earned on a 2000k deposit won't be that much to begin with.
I know that growth is not linear, but will a small amount really matter? Should I put in the 2K or wait a bit and put in more when I have more? I'm 22.
