I went through your translations and I can confirm that your translations are not machine translated. Most Hindi translators use machine translations which is a shame on our community. I am myself a translator but I majorly work on Upwork and Lionbridge. Most of the projects I see on Bitcointalk are for shitcoins and the good ones are already reserved!!
Overall your translation quality is indeed very good and I am surprised to see someone actually doing the right translations. One suggestion that I would like to give you is that you can surely benefit from a through proofread of your translations. Otherwise everything is perfect. Keep up the good work.
Thanks for your honest feedback. Truly appreciate it. God bless!
