You're right.Knowing the fact that there are already countries who have come to adopt bitcoin,so there are really high chances that our very own countries will also adopt it sooner.Bitcoin may not be use today to buy for some goods,but hopefully in the next years it will be benefited already by the mass without the presence of an exchanger.

The revolution has already started, especially in the Dubai area where they will use blockchain to reduce administration fees. Now we are just waiting for supermarkets to start accepting bitcoins

It is nice to use bitcoin in businesses but am sure if one thing that many are considering before accepting it ,which is the volatile and that alone can make any business that does not understand this go bankruptcy and the business will close shop , but if there is a way it can be immediately convert to fiat when collected as means if payment and verse versa then it will be a kind of save , so people using it on daily bases are different to company which always look forward to the profit and the sharp dip of bitcoin can make them close shop and that I see as the major reason many have not really fully accepting it .

In almost all of the countries, bitcoin has not been adopted yet. There are a few places that bitcoin is accepted. But we cannot say that bitcoin is being used as a currency.
Most of the people who have invested in bitcoin are holding their coins. They are not buying things with bitcoin. But they are hopeful that bitcoin will become a common currency. Not because of using bitcoin as a payment system. They want bitcoin to be adopted. Because that time the price will fly.

Well, that's a tricky one there. Actually, it's not about how many of us using the platforms or coins but it's about what many of the projects promised and if they're really delivering what they promised.
It seems the surge of ICO brought many inconveniences in the cryptospace and this major correction we're in is also helping to clean that mess.
Maybe when all is said and done, we'll get the good ones that we can trust and safely use.
