I know bitcoin and other cryptocurrencies are not the key to get rich, but the fact that you can gain so much from it I would not stop using it. And I believe that there is a great purpose for cryptocurrencies in the future, we might just be using it as our daily driver to our transactions. I don't usually say this, but cryptocurrencies has the biggest shot for the world to adopt in the near future to make the cashless society dream come true.
Both of these coins are have become my favourite lately. I have sold most of my altcoins and have diversified it into bitcoin and ethereum equally.
Though I am hoping that it's price will increase exponentially in future, I am wanting to use it for payments in future which is why holding more coins would benefit me in the future.
