Chain analysis reports that Bitcoin Payments down 80% in 4th Quarter of 2018

Several things are to blame, including scalability of Bitcoin transactions (and the expensive nature of them as a result) and the volatility of the currency itself. In order to have mass adoption and continued growth in the retail payments sector, more retailers will have to accept the currency. In order for that to happen, market conditions must be met and retailers must see it as an added value.
