Bitcoin is the only crypto actually being used for anything. Nothing else is coming within a fraction of its capacity being strained. The fancy claims made by faster alts may instantly fall apart if they were subjected to actual ongoing and heavy usage. But I'm not convinced any alt will ever be put to the test in that manner.

You must be right with one good and simple example of having quicker block time.

Bitcoin is having 10 minutes gap whereas many altcoins are having fancy less than minute gaps. Quicker block time will lead to support double spending as network will not get enough latency to have all the information of all transactions happened between blocks.

More abusing by double spending will be the problem they are going to face whereas bitcoin's future is bright as it has all the features to withstand any heavy usage too. (block size also will have its feasible solution soon).

Bitcoin has unstable price and it is the thing that investor lured because they see the potential profit to be gain in bitcoin and it helps to have great future, we should continue to use bitcoin and promote bitcoin to other people because adoption can make bitcoin stronger life.

The bitcoin future seems good. Since bitcoin was already
used by other people and its really being popular also in
other countries. Bitcoin is in demand because many businesses
use this and wants to earn more of bitcoin.

There is no proof of the future of the Bitcoin being good but I believe in Bitcoin so I think that Bitcoin is only going to become bigger later on.
Bitcoin is already doing good right now so with in a couple of years it will improve.

There is nothing whatsoever that does not have a future, inclusive of bitcoin but he funny thing is that no one knows the future for certain as we can only make predictions by holding some factors constant and in the real sense, all factors cannot be held constant. So in the foregoing, I would also make the prediction of what I see about bitcoin which is more acceptance at the same time more regulations, in addition to increase in the value from today.

Bitcoin will be featured regularly in the Remittance World

Not necessary... It depends where people use the coin, for example, bitcoin isn't a good deal for a market but it's ok to online shops and others transactions... For sure good altcoins have a space too in the world.

Not sure on what the future of the Bitcoin is going to be like because looking in to the future of the Bitcoin is impossible.
You never know what is going to happen to the Bitcoin, it may die or it may be even bigger.
