Bitcoin is a brand and nothing more. It was first. Its not the best at all. But it was the first and it has the right marketing from fans. The same as with Apple
Bad analogy, you can't compare bitcoin to Apple, yes I would agree that Apple is not the best that's why they've been overtaken by let's say Samsung as far as the mobile phone is concern.
Bitcoin is one the league of it's own, the prime mover of crypto and since it's existence, nothing has change and yet it become the top. And even if it will be challenge by any crypto in the future with better technology, it will remain the dominant coin capturing the market by 60% or more.
