The only reason Bitcoin still exists is because a lot of people are still far too attached to it to let it go. Bitcoin was the initial experiment in cryptocurrency. There are far better technologies coming that will supersede Bitcoin - Litecoin is the first of them. Bitcoin is fully unable to even act as a cryptocurrency at this point. Lightening is a patch for it. Bitcoin has now become just a holding pen for value where people that don't understand cryptos still feel most secure. Most holding it probably couldn't name another crypto other than Bitcoin. So they park value there because it's all they know and think then can ride it up. It's a sideshow. Litecoin will take it's place as the premier cryptocurrency at some point in the not too distant future simply because it can actually be used as a currency.
