For me the reason why this bitcoin is more special than the other crytpo is because bitcoin is the original, it was created first, because of bitcoin new cryptos are made and because bitcoin is very much known than other crypto. It is also special because bitcoin has always the highest price in the market and they will talk about crptocurrency, they would think first the bitcoin rather than other crypto currency.
Yup, i strongly agree with your statements. People will always prefer the things that is more credible. If not credible enough, at least as close to it as possible. And yes, because of its undeniably expensive value, people will always refer to bitcoin when they talk about crypto currency to other people. At least those who do not know much about cryptos. And of course there is the reason that its history is such an awesome story. From what it is then from now.
Which is why people should not worry about the dips of bitcoins today. Since it will clearly go up much more in the coming months this year. Considering by how much people are believing and interested with bitcoin.
