Which payment system to connect to work with clients from the USA?

Question

Payment systems

Good afternoon! Help me choose a payment system for automated acceptance of payments from clients, mostly located in the United States, with the possibility of subsequent withdrawal of money in Ukraine.
Tried through 2checkout. But this system sent me to register https://www.alliedwallet.com/
Which is not very clear to me.
Can you tell me who uses what systems. I would also like it without complex integrations)
Thanks in advance!

Answer 1

the most basic ones are scrill, neteller, paypal, payza, but if you do everything wisely, then you also need to add
paytoo, payoneer and bitcoins litecoins, etc., etc., you can cut it through the Frikassa unit. Payeer with perfect money to add some of the Americans also bring babos through them.
