But there is catch in this salary payout that the employees who are getting paid more than average payout of country can convert their extra income into Bitcoin.
I believe what you are trying to say is that only employees that are paid more than minimum wage can participate in the program, and that only the portion of their wage that is in excess of the minimum wage can be converted to Bitcoin through this program.
For someone who works like 9 hours per week, they will be able to put perhaps €5 per month into bitcoin. On average, people would be able to put maybe €5 to €250 in bitcoin from their salaries.
