Do you really believe it’s possible to implement support of all of these electronic payment systems?
For me the simplest way to pay for the service is STORJ tokens - no need any bank or electronic money system (which took fees in one way or another anyway), much more convenient. However, the problem of currently high fees on Ethereum is limiting factor of course, so I think that implementing a zkSync Era payments will solve this issue too
I have had only a negative experience with PayPal unfortunately due to my nationality. So I would not suggest to use it to anyone.
Seems debit cards works too:
And I believe that almost any bank can issue such a card and often - for free.
But you need to have a balance on it to do not finish with a frozen Storj account due to debts. So in this case the credit card would be more useful (but costly, if you forgot to top-up it before the grace period would end).
