It certainly isn't useful to the masses yet, but I think it will be huge with remittance.

They must use Bitcoins for not just an easy to use only, but also for investment and savings.

for making their lives easy.

Because they can transfer money around the world more easily,faster and with very low transaction fees. Also because it is decentralized so it isn't controlled by one central authority. Also transactions are non-refundable. There are many other reasons like the blockchain applicability in business and other industries,bitcoin price volatility speculation,etc.

No not in around the world. You can only transfer bitcoin to those countries that can touch bitcoin, of course.

Also blockchain transactions can only be done virtually so a connection is a must before someone can send or use bitcoins.

yeah, bitcoin is limited to those areas where internet is available, but still we cannot say that bitcoin access is limited as it is not the problem of bitcoin that in areas internet is not available.

well, nowadays even countries that we consider to be third world countries get a much better internet experience compared to how it was before. if the people there buy themselves a cheap smartphone that will allow them to run a light version of a bitcoin wallet, then look at how quick the nr of active users will grow. no more excuses. start using bitcoin to make a change in the world.

People should use it because you can easy pay with it, its profitable and last but not least its globally usable all over the globe!!

People should use the bitcoin because its better for payments and they can control their own money so that is also making it very nice in my opinion.
I really think its worth using the bitcoin these days.

Yeah I agree with this

It depends on what kind of transaction you are doing. If you want to buy goods or something else in real life, it still easier to use fiat for now, because you dont need few mins even hours to wait the confirmation of your tx.

You still can earn fiat by clicking ads, and fiat also has many ways to be earned.
