Like what happened before with publishers like Square Enix, EA, Blizzard. Konami Announces that PES 2019 in-game currency will be no longer available in the game due to the country legislations and rules. 

It's worth mentioning that any previously purchased myClub Coins can be used as normal and the currency will continue to be rewarded for playing the game but players won't be able to purchase them with real money.

"We fully respect the BGC's interpretation of relevant laws and made the decision to implement local changes to "PES 2019" in Belgium," said Konami in its statement.
