Guy says by investing $250 a month, he can end up with 1.5 million compounded after 50 years using ..Acorn. …What?

I’m guessing he’s basing that on some high interest rate (+super high risk) thats probably not sustainable?

I have low to medium risk investments that would not come close to that.

Yes, I could research this, I figured just asking here would be much quicker.

Just a regular Joe, thanks
