蟯虫くんに、お願いがあるんですが。
今英語でメール書いてるんだけど伝わりそうか確認してもらえないかな、国際会議の英語を是非活かしてもらえたらありがたい。
とりあえず、冒頭部draftしたから確認おねがいします。趣旨は調査依頼です。

Dear Hong Kong police department
To whom may concern,


I am writing this email to inform and ask you to
investigate a suspicious cryptocurrency company
, xxxx holdings, claims opening of cryptocurrency exchange in HK on xx/xx/2018. Refer corp.
info for details.
I am not fully aware of regulations related to
cryptocurrency and inducement activity in HK;
however, because of their multi level marketing activity in Japan, I am afraid that
there is potential violations of applicable law not only in Japan but also HK or China.
