Hello, I am a native Japanese translator. The followings are the answers to your questions.
1. Your experience as an English to Japanese Translator
I have worked at an data center for 4 years as an operator, but the job required me to translate documents and emails we had clients overseas.
2: Your English understanding
I studied English at college, and have studied in the States for a year too.
3: Your knowledge of Cryptocurrencies.
I have to say that I am not an expert of Cryptocurrencies, but I understood the documents you shared.
4: The fee you want for every 1000 words of Translation you do for me
I would like $100 for 1000 words, but it is negotiable.
FYI those Bangladesh bidders do not have translation teams. They would just hire someone else from a bidder here like me and let him do your job for them as if they did your job. Therefore, they cannot guarantee the quality of the translation.
