I frequently use Boost and Paypal because they're available both in Malaysia and other countries. I travel a lot because of my job, so these payment systems are quite practical. However, I don't like that Paypal has a monthly limit with transactions. It's bad that this limit can't be avoided in our country. That's why I have several gaming merchant accounts on different platforms, including skrill and others. That's why I have to use fraud prevention services by one payment gateway company.
P.S. I guess Skrill should be included in the list too because Malaysians also use this wallet.
