Hi Geldbart,
"I would like to invest that money somewhere so it generates some profit with a low risk of making a loss in 2-3 years"
have you ever heard of the magic triangle for financial investments (profitability, liquidity and security)? You can't have it all. You will not get a higher profit with a comparable risk. You could buy government or corporate bonds, but the ones with prime or high grade will not be better than CDs (they are even worse in my humble opinion) and if you choose e.g. emerging market bonds, the risks will be higher.
(Do you know that the bond values will drop, when the interest rate should go up? So even raising interest rates should not help you in the short run.)
There is no such thing as "a hot tip" which bond to choose. I'm really sorry - I wish there would be something I could recommend. We are currently in a phase of low interest, so get along with it and make the best of it by chosing rather safe investments.
If you said, you could wait even ten years from now, I might recommend to spend some of the money in a global ETF, but even five years from now would be way to short to invest in stocks.
BTW: Since you are considering a saving period of 2-3 years, most of the 60k-70k will depend on your savings rate. The compounded interest will be extremely low even if you could get 2-3% additionally compared to the investments I proposed in my previous post.
