If bitcoin dies, then of course people will lose interest in altcoyins.
This will not happen in the foreseeable future.
The technological revolution is becoming Informational.
Crypto currency takes its niche in a new world order.

Bitcoin will not die because of that if you have not interested bitcoin will rise bitcoin is a part of us many people crazy about bitcoin bitcoin help us a lot. theres no way bitcoin will die of disapear and lost it is a money on internet.

I think it will not happen, if bitcoin is lost, I think other altcoins like ethereum, litecoi, doge, will be used for investing.

Exactly. I mean, bitcoin is not the only cryptocurrency out there despite its recent price increases throughout the years. There are also other candidates as well like ethereum, e-toro, etc. that have a good profit-scaling ability for investments. But it also depends on the reason on why bitcoin suddenly died. If the reason involves a world-scale banning and countries have imposed certain laws about the prohibitions of other cryptocurrencies as well, then people would start looking for new things to invest on. Though it may sound impossible, it may be possible depending on the damage of it to certain countries in terms of economic impact.

bitcoin is the great motivation for us and the people is interested because of it s high value the people have invested their money they want to successful in the crypto world. bitcoin is very good for those who are new to this currency and they should wait for the profit of their efforts bitcoin is very fruitful for them in the near future.

This question never come in my thought at all, since it's now only an "early stage" of Bitcoin to gain its popularity through time. People will show more interests on it and it's totally unstoppable...

I might think about this matter, if Bitcoin reaches US$100K or more. 

i don't think that people will loose interest on bitcoins even if bitcoin die as there are several other alternative crypto currencies in the market which will come to light which are next in line of the market value after bitcoins they are as follows Litecoin , Ethereum , Zcash, Dash, Ripple, Monero. These currencies will have more value if btc dies a and i don't think that people will lose interest as crypto currencies are something which gives everyone more profit than anything else.Moreover i feel that this question is foolish for you to ask because bitcoins won't die so fast as it will take ages for the last coin to get mined and the market of btc will continue to grow.

I think Bitcoin will never end because this is the future that millions of people around the world are invested. Bitcoin helps us so many ways and make our life easier like payment of monthly bills such as water, electricity, telephone, insurance, fund transfer and many more without any fee and very convenient to us. So, I think Bitcoin will still continue to grow more and will be implemented more to other countries as mode of exchange. Also, it helps us to earn additional income thru trading by just using our cellphone and internet for our future. Bitcoin is too big to fail to so I think that will never happen.

Well, it depends on the cause of death or faltering of Bitcoins. If it falters because of better innovation that is at par with times, then yes! People will definitely lose interest in it and venture onto something else that best serves their needs at the moment. Nonetheless, if it falters by reasons of hacking, government intervention and others of like circumstances, well I guess people will continue to cling onto it until they maximize its profitability.   

If bitcoin died we cant say people lose their interest in the other crypto but it is impossible that bitcoin will be died.

Think about it, If bitcoin will be died I think we need some developer to develop some altcoin to stand like bitcoin if there is none, all altcoin will be died also because all altcoin is connected to bitcoin its because bitcoin is the mother of all crypto.
