"Excessive bandwidth usage" Problem

Hi everyone. Sorry for my bad English
Im total noob and this is my 1st time building a website.
Today, My hosting account has been suspended because of "Excessive bandwidth usage"
Contact to my hosting support, they said i need to upgrade my plan from 3$/month -> 100$/month =.=.
I dont even earn 100$/month from my website...
My site has ~ 2k unique users daily, i upload img, mp3, video (most are copyright content) to my hosting. Should i keep upload file to my hosting?
What should i do from now on? Buy sever, vps or what? Please help !
Thank a lot

you may need VPS or dedicated server if you are hosting videos and audios on the host with unlimited bandwidth.
If your content is copyright protected you can choose any USA based provider which is cheap in prices for dedicated server, but if you are looking for offshore hosting i suggest you to visit marketplace>Hosting for great offers
