How it could be popular if it has no instant transactions and you should pay 0.30 cents TX fee buying a cup of coffe that costs 3 dollars? It is not working for wider adoption. They must implement lightning network and segwit, otherwise there are no reason to talk about the future of Bitcoin. Without updates suitable for wider adoption it is dead.

The future of bitcoin is very bright.
Looking at the present growth of bitcoins,
It might become an official online currency soon.
Already famous firms have started accepting bitcoin.
Steam has accepts payment in bitcoin.
Starbucks accept bitcoin
G2a also accepts Bitcoin.
This shows the progress of bitcoin
And so it is very bright.

I secondly agree with you...

Unfortunately, SegWit is not getting much support from the miners. Such improvements are more likely to be implemented first in Litecoin. After this happens, it will be possible to see if this will bring significant benefits to the network. If such improvements prove to be efficient, I think this will bring an incentive for Bitcoin miners to also demonstrate support.

many big countries like usa, japan and Russia already regulates the use bitcoin so bitcoin not illegal goods there. therefore people are no longer afraid to use bitcoin. So bitcoin will get more mass adoption that makes the price keep rise.

Many people already know about bitcoins and they use it all the time, so it's not the new currency anymore. But in the future it has great chances to further development and ti become stronger and more adopted and that also depends on the users. If it uses its chances right it will have bright future.

Bitcoin is becoming popular nowadays and many people used bitcoin used as mode of payment on online stores and online transaction. Yet, it's not impossibe for bitcoin to become the new currency in the near future because some county like USA, Russia, China and Japan is now using bitcoin for their online transaction and online store.

Imagine having an app on your smart phone that you use “to call an angel” for someone who needs one with a “push of a few buttons.”
Imagine calling people to help you with a “push of a few buttons.”
Bitcoin empowers people to help anyone with the "push of a few buttons".
