I suggest Bitbond. It is just finishing its STO (as of July 8th), and is worth buying their BB1 tokens. They pay 4% interest each year and their cryptobond is the first approved STO in Germany. The tokens will be bought back at the same price after the 10 year maturity date. So you xant go wrong. You get any money you invest back plus the quarterly and annual dividends. Invest and get dividends every 3 months.
