I know it is an old topic. However, I would like to get some more fresh insights after the recent deep from experts and holders of both Bitcoin and Etherium. I have a little bit of both. However, I am hesitant with enlarging further my Bitcoin or Etherium portfolio. My brain says, Bitcoin will stay #1 for a minimum of few years. My heart says Etherium should grow significantly and finally overcome Bitcoun in the upcoming years. Not sure which one to chose as a long-term investment.
