Imo opinion, there's 2 ways Btc can go.
1/ It doesn't change or manage to follow up with the competition (so no SegWit 2, no Lightning System), and it survives as a Gold-Index, not as a payment method
2/ It manages to update and keep up with the competition, and becomes more reliable, fast and efficient, and becomes the "Basic" (which it already kind of is, but not when it comes to the circulation of Daily-transactions).
Imo, Bitcoin would have lost its dominance a year ago if it wasn't for its name, which is now linked to the entire Crypto game. I'm pretty sure more people know of all THIS when referred to as "Bitcoin" rather than "Crypto-Currencies"
