The site claims safer but it doesn't feel safer. The first click opens my files for me to select one to upload, yet why am I going to upload a file to a completely unknown entity? Who is/are Mega? What gives user confidence to entrust (confidential / personal / business) file uploads to Mega? There are a few steps missing here, I would work on building customer confidence. Unless you are aiming for uploads within a network of people who know and trust you for other reasons. Good luck.
