the vast majority of his ig followers = thirsty females who could give a fukk about his music, they just think he's attractive theyre not checking for his music because he doesnt make music for them anyways
he gets posted on shaderoom/balleralert all the time thats how he grew his ig following
if I had to judge his actual MUSICAL fanbase he definitely has buzz in the tristate but he has yet to capitalize with a hit and buzz comes and goes so if he doesnt do something within the next year or so he might as well just secure that modeling career and hang the music shyt up before he's vado status, he's pushing 30 anyways
tl;dr - 10k-20k fw
Nah, Dave is one of them artist that's most likely gonna go the O.C., Masta Ace, etc kinda route, respected but not mainstream, may have a couple of minor major buzz songs. But will mostly build a solid Hip-Hop fan base Stateside and more importantly overseas.
Tour on a regular basis, ghostwrite, release projects to a dedicated fan base, basically be a working artist, like most are.
