That is completely true, bitcoin is more promising as it is only in the short period time we can already make money with a good trading technique. Gold will guarantee you profit in the future and it is more safer but the reward is not that high, gold investment is for the rich only.
Me either I'm preferring to choose bitcoin at all because if we are going to talk about investments with gold that is really hard to acquire.
And bitcoin is really promising at all and it is much easier to have investments to it and you can easily manage it too properly.
But they have both characteristics, they are increasing as the time goes by.
