You are absolutely right. But I think it has more to do with governments than with the projects and it's not an inherent problems. The licenses for Payment processors requires immense fee's so it's somewhat hard for relatively new payment processors to offer quality services. I know it's not a good excuse but still that's how it is.
Established payment processors such as Skrill and Paypal has no such issues but the problem is they are hesitant to enter this space.
