I prefer bitcoin, for me it is like a digital gold and it can be easy transfered whereas gold is difficult to hold and it need to be kept in some kind of safe. What is more bitcoin will be bigger than gold so please choose bitcoin,
For long-term investments I agree with your opinion, it's better to save bitcoin because indeed this investment is a long-term investment and requires patience and research that is always updated. if you want to save gold there is also a good thing but with the benefits obtained it is clearly very different, more profitable for bitcoin.
