That was a great review you did.

Another aspect where Blockchain Technology could be helpful is the in-game purchase, already the Clash of Clan game makes use of Fiat currency which requires users to provide their card details before a purchase can be made. The downside to the use of fiat currency is that the users' card details could be leaked out by hackers and also unnecessary charges are taken without the users' consent

Yes, I do second your point, when blockchain technology is employed, it would help curb fraudulent acts including the above-mentioned as details of users would be hidden and secured from others.
