I love how no one is calling the lifetime membership a scam, because it is not a sustainable business model. I can see the limited membership a pretty cool idea tho.
The lifetime membership is not a scam, it was created because i was approached by someone who suggested I make a lifetime version if the membership, so i did (and they purchased it). It actually is sustainable because there are plenty of projects out there to make coins for (yesterday i got the approval from Sia to make a coin for their project, and recently ZCoin approved my design, which is now available for pre-order). I'm growing in the amount of projects I make coins for every month!
Yea, the limited membership is solid (gotta give credit to the PirateChain team for suggesting it to me) due to the amount of benefits you get. I try to make sure that the customer actually benefits pretty well to justify it.
I dont think you understand what sustainability is. Eventually, from the lifetime membership you will have spent over the cost of the membership in coins and shipping.
