I own both, plus silver.. I think they all will do well, for the same reasons. However, I have a very long term hold/outlook for them as an investment.
Yeah both of them are great to have a long term investment and both bitcoin and gold are having its price rise yearly so having a long term investment to bitcoin and gold will be good in the future.
Around this time it will be better if you are choosing Bitcoin because as you can see now you see that the value is now not that low now so that is nice.
Gold is a strong currency and that is nice because there are on this time a lot of people that is still using Bitcoin.
