At $1.99 for 1,600 Ink, the exchange rate is roughly (rounding) $1:800 Ink, all the way to the highest tier, $49.99 for 60,000 Ink which is roughly (rounding) is $1:1200 Ink. When that person decides to spend the Ink, a second exchange rate is applied when in transit to the creator, however the second exchange rate is not dynamic and is fixed at the highest tier of $1:1200, which explains the discrepancy outlined in this topic.
See, that "discrepancy" problematic for me. The company is taking out their fees at both ends, both when ink is purchased (and I assume when earned via ads/surveys that the company takes some of the revenue before awarding an amount of ink to the watcher/surveyed) AND after it is tipped.
The system seems intentionally opaque to allow the true fees to be obfuscated. A supporter recently gave me 100 ink. That translated into 8 cents before the "Est. Fees and Tapas' Share" of 1 cent was taken off. If all the fees are taken there, why is Tapas also taking some off the top when the Ink was purchased?
A more transparent system that allows everyone from time or purchase to time of donation to have a better idea of how much $$ is actually getting to creators per dollar spent, and where and why fees are taken off each time seems to me to be necessary.
If the transaction fee when ink is purchased is significant and explains that amount taken by Tapas at that point, say so. Make it clear upon purchasing that due to a transaction fee with paypal or credit cards or whatever this much of your purchase is taken off the top. Or frame it in such a way that supporters can understand how much Giving Power they're actually purchasing.
I don't have much financial skin in this game, mostly using Tapas to try to expand the audience a bit, but this lack of transparency with Tapas history is definitely scaring creators away from using the service.
