What kind of e-business would you do with 1k EUR / month ?

Hi guys! I have 1000 EUR to invest every month. That won't be long , maybe 6-12 months maximum, so until that time I want to find ways how to earn online. I need your opinions , suggestions , what are best ways to earn online now with my investments? What would you do with this money? Some people adviced me to do cryptocurrency, some told me about dropshipping, another guy told me to do instagram marketing. Maybe you can help me?

Please Help.
Thanks !
I didn't find the right solution from the internet.
