I thought Black Friday is normal for in store shopping? If that is the case, the there is little impact. Bitcoin is good for on line shopping.
That is true. If people use bitcoins for online shopping then their will be a some demand for bitcoins and it may impact slightly on prices but may not be much because as of now not many major online shops accepts bitcoins as a payment method. So I think because of black friday sales there will be very slight impact on btc prices.
