Never, remember for the rest of your life, never use your bank account for dubious transactions.
This income is not worth your risks.
This money can be criminal, and you will be a member of the criminal community because you make a profit. They want to use you as a drop.
Yep, that's how you become a money mule:
https://en.wikipedia.org/wiki/Money_muleThere is a chance that this whole set up is perfectly (or at least mostly) innocent and that the counterparty has other, not necessarily illegal, reasons to be extra careful -- but chances are that there's something shady going on and the legal implications are definitely not worth the risk.
Thanks for the link to the article, but in Russia such people are called "drops".
And besides, this is not Russian slang, but this name came from foreign darknet forums.
A deposit is not required in these schemes. The drop usually hands over his bank card and SIM card, to which the personal bank account is linked, and other people manage the account.
If it is necessary to make bank transfers, then intermediaries go with the drop and even live with him for several days in a hotel until the transfer is completed.
This is not always a criminal activity, many such services are used by cryptocurrency exchangers, but if there is a crime in the transfers, then the drop can have big problems. For example, if earlier there was no criminal liability for this, now such drops are made members of a criminal community and this is an aggravating circumstance.
