According to the CoinTelegraph article 5200 Keplerk tobacco shops will start accepting bitcoin payments in form of coupons. I think they not only accept bitcoin payments but also enable customers to buy bitcoin coupons that I think are redeemable but their partner Bitmedia or maybe they are only usable withing their shop network. If anyone here is from France and can share his experience with this I would appreciate.

5200 locations accepting BTC as a payment adoption is huge in my opinion, not only that but it is mentioned in the article that giants like Decathlon and Sephora will start accepting BTC by 2020. What do you think is the quickest way to adoption? Big retailers or small local tobacco or coffee shops which people go to on a daily basis?
