That was a typo, I meant 1%/day. In my country, there are safe investments with guaranteed returns of over 12%/year (prefixed federal bonds). For instance, if you buy a LTN 010118 right now, it will return 13%/year (before taxes) when it expires on 2018-01-01 (the current buying price is R$ 684,17, it gives back exactly R$ 1000,00 when it expires). Of course, that's if you don't look at the inflation. With inflation currently at 6.5%/year and rising, the true return is more like 6.5%/year before taxes, and more like 4.5%/year after the 15% tax on investment gains above 2 years. So yeah, if you do consider inflation, 1%/month is too high.
