Depends what your hometown is
If it's not NYC/LA/ATL (maybe throw in Miami and Houston) it probably doesn't matter... your city doesn't matter in hip hop anyway
It also depends how you're trying to come up
If you're trying to be a pop artist, trying to be some super underground lyricist, or trying to exploit the internet with hipster imagery type shyt you can come up without a local fanbase imo
