> Extremely annoyed by seeing this minimum applied only to the EU countries!
I would take a 100€ minimum over a 320% increase in transaction fees (2.9% vs. 0.9%) and a 130% increase in fixed per-transaction fees (0.10€ vs. $0.30 at current exchange rate) any day of the week.
Unfortunately it's interchange + 0.9%, not just 0.9%. Interchange ranges ~1.2-2% so the difference gets much smaller.
With a 100€ minimum the 10c transaction fee becomes 10c only after the first 1000 transactions (1000*0.1=100). If ignoring the variable part of the fee (%) then the break-even for this 10c vs 30c transaction comparison is at ~333 transactions. For a new company it takes a long time to get the first 333 monthly paying customers.
