Bitcoin isn't antique and there aren't any other crypto currencies with better underlying technology. The thing that people fail to understand is that the mass isn't using all the fancy features other crypto currencies offer. People just want to transact with the outside world, and that as quick as possible, and as cheap as possible. In other words, the technology isn't really a big deal in this case. The only thing that matters is that Bitcoin is by far the most secure and powerful network, has the best developers working on it, the largest and wealthiest ecosystem, etc. On top of that, you can test lightning network for yourself to see how fast and cheap it is to transact off-chain. It is a perfect adoption stimulator.
