If you are going to invest than there will be a chance that you can earn some good money so that you will have a lot of money later. But there is a risk that you also can lose some money with making an investment.
well, with saving you have some sort of safety, yes, but while everything in real life gets more expensive, your savings account's interest rate can't keep up with that. that's why people get happy if their somewhat safe investment in stocks for example brings them 5-10% interest per year. that's considered to be a very decent return for a low risk investment. and investing in bitcoin will bring you even more return.
