You can always use
https://www.seoclerks.com there are a bunch of people selling tweets from their twitters on their. If your feeling nice you can PM me and i'll send you my ref link and i'll give you half my earnings.
I will take a look there, I'm trying to reach a large audience (real/human)
Why not advertise on this forum or i can display the ad in my
signature space if you want it the cheaper way
I know that i can advertise here, but the niche has nothing to do with bitcoin.
if you are interested in a facebook group with 16k+ members just send me a PM so we can talk about the rate. dont worry i dont expect much about the price
I need to know what kind of members does your group have, I have sent you a PM.
