Just like basher they trying to bring down or contradict what others belief .Probably they experience negative things as you've exampled so they frequently say its a scam and bitcoins will die . Don't bother to listen on them and as always said invest what you can afford to lose so it is not too depressing if what will happen.

Well, eventually it will die, but I think you'll get the return on your investment first. 

There are way too many people predicting the future and they're usually wrong.

everyone will certainly do it all. Without exception those that already have the perfect life. They do it all because it wants to make the spirit from within them to grind it in a way that is better and the maximum. I think you also do the same thing with them/me too. So, this is not something a bad thing cause it to make or uplifting yourself

Lol lots of peopel are telling you that the bitcoin is going to die but i dont think that is going to work becuase i know that the bitcoin will not die not even in 10 years
for sure so believe me not them,.

I don't see bitcoin going to die anytime soon so that your sons/grandsons may also be able to use it however there will be always new thing coming up daily in this modern world and there is also chance for bitcoin to get upgraded or replaced by better solution in future.

I also trust bitcoin like many do and also saving few of my savings in bitcoin for future but i keep on checking what is happening on bitcoin world so that i can sit relax with my investment. Don't save all you have in bitcoin could be best suggestion.

I think we don't need to worry about it. It surely can "die" someday, but it won't happen now, or soon. Bitcoin has a prosperity age yet to reach, and we will make much profit with this crypto-currency.

But it's normal that material things arise, make success and disappear or lose its price then. But I believe it won't happen with BTCs until the next generation.

Well your on luck mate it will be a super long time when that happen, What I mean is that Bitcoin won't really die in terms of it non-existing anymore but in terms of price decrease maybe it will happen. Also the momentum of bitcoin's popularity increase everyday , popularity=demand. Demand is the main driver for the bitcoin's price of course I can see a bright future ahead of it.

@op, if you counted the times people talked and speculate about bitcoin death,  you would be amazed that it was speculated several times.  But as you can see, it is a mere speculations,  no proof or fact behind it.  These are the minds of people who wants to get bitcoin at a very cheap price.  They are spreading F(ear)U(ncertainty)D(oubt) in order for them to buy Bitcoin at their target price.
