Dear all, I have received some bitcoins as a donation. The person sent me by Whatsapp a QR code and a code with 34 letters and numbers all together (it is not the 12 words master seed). This QR Code is a printscreen of the Mycelium app. How should I proceed to receive these bitcoins? I have already created an account in a bitcoin wallet but I don´t know how to receive the transfer. Sorry if it is too basic! I am a beginner! Tks!
