Definitely bitcoin is number one in the rankings of the currencies simply because it's value is high.
Another proof is there was a time when bitcoin has defeated gold so it shows that bitcoin is really number one.
I am highly impressed by the decentralized nature of bitcoin currency and the way it increases and decreases in value. It gives you countless offers for becoming what you exactly want to be in the world full of competition and struggle. Bitcoin leads to your financial freedom.
Bitcoin will never ever give its position to anyone else because of the love it is enjoying from the people all over the world. Bitcoin is number one crypto.
