because bitcoin is recognized as the best coin in the world
I'm wondering who recognized bitcoin as the best coin in the world? Or is that just your opinion? You don't need to pass off your opinion as the opinion of all people. No, I don't mean to say bitcoin is bad. Bitcoin is definitely one of the best inventions of mankind, thanks to Satoshi Nakamoto. But I think it's wrong to make such an unsubstantiated claim about the best coin in the world.
That is without a doubt a massive assumption by the OP, do not get me wrong when I compare bitcoin to every other altcoin, precious metals and fiat, bitcoin comes ahead easily, however bitcoin is not really recognized that way by most people yet and in fact we are a minority as only a small amount of people hold any significant amount of bitcoin, while the rest of the population is not interested in holding bitcoin or they believe bitcoin is in fact a bad coin.
