we don't know but if we look in the positive side there's no reason for the user to lose interest unless their rich enough and contented what they have right now and I think or there's still a possibility that the bitcoin can be the money in the future if we continue to use bitcoin it will not die and as long as there is money here it will not die.

I don't think people will lose interest in other cryptocurrencies if dies because bitcoin will never die without a failure somewhere in it. So, if other altcoins can provide the solution for the bitcoin failures then people will turn to them and continue using them like the bitcoin. If bitcoin die, I'll definitely turn to ethereum.

I think other cryptos will be completely meaningless, because in my mind, bitcoin is a belief of other cryptos, and it will be the last crypto currency to disappear,

I do not think people will lose interest in bitcoin, if so there is altcoin that will replace bitcoin

I do not think that if bitcoin dies, people will stop investing in altcoins. On the contrary, bitcoin can die because investors exchange it for more promising coins.

i think its not . im comeback to this crypto party because seeing the btc price again .
so i should said current price now make a eye of the world to seeing about btc again .

I don't think bitcoin would die. It is still stay strong.
If you ask me what would I invest other than bitcoin, I would say Ether. It is used by most of projects and faster than bitcoin.
EOS is good to invest too

There is still possibility bitcoin will be dead because first, it is already been gone by its developer. Even it is decentralized, many still patron it and invested in it. Even in the circumstances that major holders of bitcoin sell their interest, bitcoin price will surely go down, declined, decrease. If that is so, that is why other cryptocurrencies rather than bitcoin is called alternative coins, what we all know and commonly use is altcoins, is it could replace bitcoin as the central coin. Nowadays, many investors do not just invest quickly without just researching first for where they put their money, in this sense, the risks of lose or losses will not eliminated yet is minimize. People aren't losing confidence even so bitcoin will not be the star among them all.

I don't think that actually . may be people  are thinking that etherum and another altcoin have more potential so they are investing on that. But I don't think bitcoin will died . I hope bitcoin will again raise up very soon.
