sometimes when we buy any item with bitcoin, there are a lot of discount we can get, as example if we buy laptop or gadget, we can get discount until 20%. If this is continues, maybe I will always paying anything with bitcoin, hopefully this is always happen when we shop ...
I would like to know who is paying for those discounts. The merchant, because he likes bitcoins? Bitpay, to attract new customers?
One sad fact about bitcoin is that there is practically no reliable data on the bitcoin economy. The few numbers that we have (such as the transaction statistics from the blockchain, and the trade volume at the exchanges) are hard to interpret because they may include large fraction of "fake" traffic, and/or miss a large fraction of the real traffic. For example, we do not know how much Bitpay and Coinbase are processing per day, and what kinds of good/services dominate. We do not know how many bitcoin owners there are, and how the bitcoins are distributed among them.
