I think a lot of people stopped spending Bitcoin, because the price is so low and they know the price will increase in 2016 after the halving, so they would rather hoard it. The
merchants will give up on Bitcoin, if they find that the transactions with Bitcoin as a payment method is too low. Once the price increase after the halving, merchants who have
stopped accepting Bitcoin, will kick their own ass... It's just a bad spending cycle now... It will pick up again.
