Hello chahermosa
Crowdfunding is a very difficult and time consuming way to fund a thesis student film. The main reason for that is that crowdfunding does not mean that random people give you money for your project. To be successful you must have a fanbase and people that want to see your next project. Usually thesis films don't have an existing fanbase. As well you must marketing a successful crowdfunding campaign in a smart way. That all needs a lot of time. And at the end you must please all donators which is as well something that costs you resources.
However, I have experience with crowdfunding campaigns for thesis films. I was involved in such projects from Morocco, Pakistan and UK. In case you have a good story, a great and motivated team and the budget is realistic, feel free to get in contact and I may can share some ideas.
Kind regards
