Well I agree with you, but we are not quite there yet. Bitcoin can achieve all those things, but we don't yet have those fast transactions and with low fees. If you compare bitcoin transaction with Visa or paypal, you will see that those are much faster. Also our fees are better now, but still not as low as they need to be, in order for us to use BTC for small transactions (like grocery shop etc).

I do believe that we will be able to achieve that in the future, so yes, in the long run, if everything goes well, bitcoin will play a major role as a currency. Right now, it's a good investment in my opinion, because like I said, I think it will achieve all those positive aspects you've mentioned.

I think it yes, with all of these advantages of bitcoin to make people at ease and happy in their lives then the role to help the humanity is already achieved. Most of the people way of living were lift up because of bitcoin it is already a part of the world history of mankind for the next generations to take.

i also think that there is no doubt that bitcoin already play a very important role in life of people and even will play in future, in fact some people already depending on bitcoin for their living and if in future bitcoin become more stronger and reliable hopefully their living style will become improved from time to time, i think in future bitcoin will have a very important role for the people who are mostly depending on bitcoin.

Bitcoin is the pioneer in cryptocurrency, and as we see the world today, technology is moving fast, no doubt bitcoin will play a major role in the future. As of now we are seeing a lot of people bashing bitcoin, however bitcoin has proven itself to be stable and  had proven to everybody that bitcoin is a legitimate currency. I think we are just seeing future being born this point of time, it is like taking care of a baby, and after how many years, we will see that bitcoin will cost a fortune, and all other technology will soon follow on how bitcoin was created, just look at altcoins, thry have a the same technoloy but it is being produced in a deifferent way, somehow. Bitcoin will also play a major role in all countries, the more bitcoin you have the more power you have, i think we will see thins that had happened before just like when people are using gold and silver coins, the more gold you have, the richer you are, and gold back then is also being mined, not being printed just to have a lot and devalue it further. Let's all just eait and see what will thr future holds for us and bitcoin, hopefully all will turn out postivr 3-5 years from now, then another 10-50 years, for us to see further what rope bitcoin is playing for the rest of the world, not only in currency but in technology as well.

yes that is right that bitcoin has to play a very important role in future, actually bitcoijn is becoming more and more popular from time to time and as more people are investing money in bitcoin and making it more stronger, therefore we can believe that bitcoin will really play a very important role in future, specially in modern areas where people are more educated and like on line business and shopping etc.

I think bitcoin already has the potential to be a part of the future and a role to play in the future because people in the future will be mostly using technology in their daily activities. It has already started and well never know what the future will bring also.

The short answer is yes.
However i have a bad feeling that as the world moves to digital currency, bitcoin will be used as a model for future currencies but replaced by a coin decided by the world banks.

Based on all these aspects, I still think that the role of bitcoin is to be the unifying factor for the international currency, be the global currency. Today the US dollar is the strongest currency followed by Euro and Yen. If the bitcoin becomes powerful currency in the future, all international transactions will be based on bitcoin currency.

yes i think in future Bitcoin will be a shining currency more than currently, I think to understand these it is very simple you check the price of future you can watch how bitcoin price rapidly grow and no one can constantly break it so in future rates are depend some time in news but it will go up and high.

Why not?! Borderless payments without third parties involved taking your information and collecting fees. What a racket. No more, the people only need other people;)
