All investments fluctuate depending on the market. Therefore, it is normal to see short-term fluctuations (up and down) in your Finhabits account. What you need to understand is that historical performance shows that investments are likely to grow over long periods of time. We didn't make that up. It's just how the math works!
It's important not to overreact and pull your money out when you see your account go down. The ups and downs are completely normal. Keep your investment active so that it has enough time to grow.
