Bitcoin is evolving which is the reason it should be chosen but there is nothing bad to diversify. If people learn about how to avoid scams and hackers, bitcoin theft will significantly reduce but people will always be people, they do not care until they lose.

Bitcoin is still going to tens of trillions of dollars in market value and later likely will compete with gold. It is truly the digital gold.

If you ask me which one I will hold. Then my answer will be I will hold both. Because Gold and Bitcoin are two very strong investment assets. One is physical and one is virtual. But when I invest in Bitcoin, I will sell it first for any need because selling Bitcoin is very easy. But if I invest in Gold, I will not sell it very easily because selling it is a bit troublesome. To sell Gold, I have to go to a gold shop. But I can sell Bitcoin very easily from home. That is why I will employ both assets to hold my investment. Because even if we decide to hold Bitcoin for the long term, our psychological issues will always be more motivated to sell Bitcoin for any important need. So since both investments are very strong, I will choose both assets for investment.
