I personally think a basic income is the wrong way to go.

I see only 2 Ends to this:

1. Prices adapt to the higher income to a level where the basic income is just enough not to starve.

2. The lazy nation argument.

This is IMO the wrong direction to handle the problem.

Making Germany more attractive for low income jobs would be way to handle unemployment problems in the long term.

For example:

The company I work for is currently shutting down its complete production in Germany an reallocating it to Hungary, Romania, Mexico and China (don't worry I work in development so I'm not affected, ...yet).

Our assembly workers earn 1.400 to 2.200 € a month, you see this is only slight more than the proposed basic income. If the state would have used the money it now pays all this workers for their current unemployment instead to make production in Germany more attractive, these people would still have a job and therefore paying taxes. A way I could think of would to pay companies a bonus or a tax reduction for newly created jobs (a way to prove this is really a new job that wasn't there before must still be thought of).

Kind Regards
