i am a Lead Engineer who usually give a training session to my subordinate, and this platform could be a lifesaver because i don't have to spend all day writing content, but my problem is there should be micro pricing strategy on your method, you could refer from mobile legend, they sell very low quantity of diamond with a price less than $1, and we ended up buying more. i appreciate the initiative that we could use "GOPAY" as a payment method since it is quite popular in Indonesia, i hope i could by small qty of credits just according to the features i only want to use.
