i'm sure we'll see a bitcoin icon in every store's door in the future,bitcoin would be widely used just like paypal to buy things,delivery,or even pay taxes
it'll become just like paypal,but the different,it's currency,bitcoin will not going replace the fiat because bitcoin is digital,i didn't thing bring a coin is an effective way

Yeah we will seeing many stores in future, We need to wait for that but the scenario will change in future where we would be able to spend our bitcoin directly.

not yet for this year,i believe bitcoin developer and bitcoin expert still focus on bitcoin project like bitcoin halving and open bazaar. hope next year will comeing soon,its would great to see bitcoin store.

If you are so much enthusiast then i would recommend you to get a bitcoin (virtual) debit card and spend your bitcoins mostly everywhere like the normal debit card. But spending directly your bitcoin is a bit problem because it is not implemented in lots of countries.

Maybe checking the balance at the ATM charges us but haven't used it yet because the companies that offer these bitcoin card are online (mostly exchanges like ecoin bitx cryptopay xapo etc) and we can check our balance directly online and without any additional fee.

Why need of a store to transfer our bitcoin. Everyone can do of their own even with mobile, We will see large number of stores accepting bitcoin in the future which is the key factor for large adoptions.

I'm pretty sure that yes we will... The widespread of ATM's is a good signal for it...

Coffee shops? How about banks? I've been dreaming for years to buy BTC at a bank or a change store. Nearly every month, I buy or sell Swiss francs, Hungarian forints, British pounds or some other currency. It would just be immensely convenient if I could buy or sell BTC at those same places.

lot of people still dosent know and if they sees a store they might ask and know more about this and have more trust.

It will happen in the near future because brazil has 150 store accepting bitcoin as payment and here in my country they are planning to add bitcoin in our government.. so it will legal in my country..
