People could lose interest because of this swings wich are not happening only with btc but with all crypto

Of course people will never get interested with bitcoin if it is dead because is it's just a waste and useless if it is dead or what we call a worthless one. I think ether is the crypto that will become popular since it was a second strongest crypto in the world. But I believe that bitcoin will never be worthless and continue to grow.

Since it all started from bitcoin, I mean the the technology behind digital currency, crashing of bitcoin in the market will definitely have a negative impact on the entire cryptomarket. However, The way I see it right now, bitcoin is really far from over. The international market seems to be  embracing the technology and finding ways on how it will become beneficial on the global industry.

For now the people are interested in the crypto and if the people lose to interest in the crypto then the market of crypto will down but because of the bitcoin growth the people are coming to this currency and they want to show interest in the crypto and it is good to invest now in the crypto while for us the bitcoin is very useful for online payments. People will show interest in the bitcoin if we motivate them to the crypto side and it is good to hold some of the investment for future.

I don't think so, though bitcoin somehow became the foundation of altcoins specially when it comes to acceptability among different users and they complement each other in the market and in every transactions that doesn't mean people use them because of their similarities nor popularity. Altcoins are now flourishing not because of bitcoin but because of each individuals altcoins' uniqueness and nature as a cryptocurrency.

I think it is impossible, people will not lose interest to the bitcoin because bitcoin is continuing to give blessing to our society. Observe the people nowadays, they are becoming interested to the bitcoin because of the advantage that they can get by using bitcoins.

no.never

No people will not loss interest.  All expect gains from bitcoin in future. 
But if they loss interest they will not invest nor will they earn. To earn they have to keep interest have patience too.

With all the hype and fervor for bitcoin, I think it's hardly happening in the near future.

So we'll do our part to encourage it more to stop it from ever happening.
