Also is more attractive for me to get paid this way because I don't have to worry about maybe having to explain to the authorities why I have four or five transfers of couple of thousand each, from different guys.
You can create a new bank account solely for the purposes of your transactions related to your business. And I wouldn't worry about the authorities breathing down my neck because of it as long as I have the records of a business transaction had taken place when it comes to the exchange of goods for cash, receipts are ideal but records of negotiations and bank transactions as well as proof that the product exist can be sufficient for you if you are asked about it. You might even be at more risks if you tried to mask your business transactions via Bitcoin and don't report any earnings at all. As long as the business is legal and you are paying tax I don't think you have to worry about anything at all.
