Today, I finished translating 4 new articles on LearnNearClub. Here is the details

=> Total estimate: 85.5 NEAR

@cuongdcdev will review my translations.


Thanks @baoanh1310, I have reviewed and edited them all. about the payment, the NEAR price is now around 2.22$ so we need to adjust the price a little bit.
So the total estimate for the translation is 77 NEAR
The review cost is 16 NEAR
