bitcoin acceptacne, could have done by simply including a bitcoin core into the screen payment system stores are using, however, all of them would have to accomplish all the blockchain. since part of them would not able to do that, or they were weighting too much of their profit, they decided not. like in Hong Kong, accepting bitcoin could have made instantly - they don't want to.

For some people, gambling is part of their everyday life, they literally can't live if they don't gamble or bet in some way. Which means that Bitcoin has already been adapted into some people's lives.
But for other people, Bitcoin has also been adapted into online shopping as well as real life shopping which is really great. I don't know what will adapt Bitcoin next, but hopefully it makes Bitcoin even more popular.

yes for now bitcoin is not everywhere yet like you said it's because not all people know about it
and for your question what the kind of everyday life needs which will adapt bitcoin
the answer is gambling, everyday bitcoin user who love gambling will use it to gambling and the second is online shop

Bitcoin is not yet everywhere because there still some countries that don't accept bitcoin and also there is a lot of people who didn't know what is bitcoin yet and what are the advantages of using bitcoin. If bitcoin will be popular and introduce in different social medias then it can easily spread to anywhere and soon you will see bitcoin everywhere.

I think you can really see bitcoins all over the world the problem is not a lot is using it physically and there are just a limited merchant online that are accepting bitcoin I really think that bitcoin can attain the position of one currency in the future but for now it will be very difficult because the government doesn't want it cause bitcoin does not have tax and it is not controlable for them.

I can speak about my country, Croatia.
We don't have so much users and only a few offline merchants accepts bitcoin for payment.
Recently, we got 2 btc ATM's and it's all.
So, I don't have much options what to do with my btc funds.
I can't spend it offline, only online or keep all funds in the wallet.
Hopefully it will change soon.

Well if you don't know what to do with your bitcoins you can exchange them for fiat currency right? I have a few bitcoins and sometimes I exchange a bit of them to pay for the bills and groceries and stuff like that. Most of them I keep in my wallet for long time investment.

It's not because only that, most of the people still prefer using fiat over bitcoins even though they actually know about bitcoin and there might be a lot of reasons for that... First of all, fiat payments are accepted everywhere so you don't have to bother searching for special shops or something, moreover governments some time are against bitcoins so people are scared to use it. I think we just need some more time and bitcoins will be everywhere and people will use it all the time instead of fiat.

Fiat is an abstract concept as such

There is no just fiat, it is always a certain currency (e.g. US dollars, euro, British pounds, etc). If you are using a local currency (whatever it might be), you typically won't have any issues with buying usual daily stuff. But if you are traveling around the world, converting one fiat currency to another may give a lot of headache (if not butthurt), and this is where Bitcoin shines. You can access your bitcoins from virtually everywhere and convert them to whatever currency you may need at the moment. Basically, only the US dollar comes close to being more or less universally accepted across most countries

Online shopping. None physical services like subscriptions to ISP for internet cellphones etc etc. Will then move on to ordering online pyhical items and it will just roll on from then. More and more places will start accepting it in fear of being left behind and they need btc customers too they would not turn down money in any form.
