Then if that there is a coin that can surpass bitcoin that coins must have better concepts or technology
Stated that bitcoin gains its value as oldest and most trusted chain its hard for other coins to beat that, It hasnt have to be the tech or concepts but could also be a trust swing.
Yes, but at least if one coin wants to beat bitcoin, then that coin must have more benefits than what bitcoin has. We don't know because until now bitcoin still the strong coin and bitcoin still lead the cryptocurrency so we can say that it will be too hard for the other coin to beat bitcoin. I think we need to chase the next coins to be the next bitcoin because bitcoin already becomes the best coin in cryptocurrency.
