Bitcoin is not going anywhere, atleast not in the near future... We may see some other coins with bigger growth during the next years but probably not enough to overtake BTC as the 'main' coin in the crypto market.
No mate, bitcoin is going into the top list of crypto currencies and it's not about to die soon. There are a lot of people that are sticking and saying that they will put their faith in bitcoin. And I won't say that there are just some other coins that will "take over" bitcoin, it has a big support from the community, companies, establishments and citizens.
Bitcoin is leading and definitely the future. I will hold on to my btc and don't sell. In a few years there are so many people who had wished they'd kept them. Bitcoin will be more well-known and more accepted in the future. Can you imagine if a few major internet companies will accept bitcoin payments...
People let themselfs easily scare by bad and fake news. The one with patience will be rewarded.
