people who hear the word bitcoin and other digital currencies. certainly curious and find out about bitcoin, let alone the benefits to be gained is very tempting, people - people will be interested.

Unfortunately yes. There is a great possibility that it might happen especially during this time that other people are in doubt with bitcoin. They have been carried away by the fake news or whatever negative comments that they are reading about bitcoin.
But it is a personal decision based on the current status quo of bitcoin.

i can't see it as people losing interest, bitcoin is the future.

i think a lot of alt coins could fail, people could lose interest in these most of them actually have any fundamental value.

I do not think they lost interest, I just do not understand what's going on.

I think the losing interest of investors are temporary and it will come back soon in the next month.

I don't think Bitcoin will die. In any case, the interest in the cryptocurrency will live for a long time. It's just getting started.

If bitcoin for some reason suddenly disappears, then I do not think that it will be a catastrophe for other crypto currency. Each type of crypto currency is able to exist independently of other crypto-currencies. The only thing that connects them with bitcoin is the binding to the bitcoin price on the exchange, exchangers, etc. However, such an artificial binding can be reoriented to other coins, for example, ethereum, litecoin, bitcoin cash or other well-deserved digital coins.

most likely if bitcoin dies, altcoin which will replace bitcoin position is Ethereum. why I say so
because so far, only Ethereum is able to dominate Bitcoin, when bitcoin up Ethereum will go up.
and on trust, only Bitcoin and Ethereum alone have more confidence than all investors. and it is not owned by another altcoin.

No
People don't lose intrest from bitcoin .Everyday new parson join in bitcoin furam .

The Crypto currency has just developed. Many kinds of crypto-currencies have appeared on the market, which not only are not inferior in terms of functional qualities to bitcoin, but even in many respects surpass it. And each crypto currency exists by itself as a new kind of digital money. However, most coins when trading in the market have a price pair of binding to bitcoin or ethereum, less often to other coins. The binding to bitcoin is due to the fact that bitcoin was simply the first crypto currency and remains the most famous crypto currency among all. However, if necessary, this binding can be made to other crypto-currencies, if bitcoin for some reason disappears. Therefore, such a disappearance will not have a big impact on other altcoys.
