I don't really invest because it's risky and things like that sometimes I do I prefer investing in crypto currencies like bitcoin I don't have much experience so I try to be as careful as I can sometimes I invest in stocksUsually, banks offer 3 kinds of investments, talking about risks: conservative investments (very low and low risk), moderate (medium risk) and aggressive (high and very high risk, typically stock exchange). When we earn an income, were offline or online and we try to not spend every cent in order to invest, we know we could earn interests in proportion to the risk level. Knowing in an aggressive investment we can lose money (sometimes it happens to moderate investment too, especially when lacking financial knowledge). Conservative investment are used to give poor interests, but usually people don't lose money (even if the amount value can lower due to inflation).
