We need to wait and find out! Amazon is very big company and if they start to accept bitcoins that will make bitcoin more popular and trusted. I will not believe in this until it happens, I`m sure that one day they will start to accept bitcoins as payment method but when will that happen depends from them. Will they accept bitcoin directly or they will use service like bitpay is also important.
26 October is a month from now, that is not far away and soon we will know is this true or not. I`m sure that this can reflect on price and maybe bitcoin can really go to 10.000$ by the end of the year like some people predicted. I don`t see what else can make the price grow so much in just few months except this, I`m not sure that even this can enough for such price rise.
