Yeah it is all the matter of choice either we like to invest in centralized assets or decentralized ones like Bitcoin. But in my own perspective people are now trying to jump into Bitcoin because of some positive events. The only thing with Bitcoin is that it is a high risk high reward investment whereas gold it is more stable physical asset that does not gave opportunities like Bitcoin.
Bitcoin is a symbol of freedom, and many people seem to want that freedom. Gold and Bitcoin are always compared, but it is like apples and oranges, because they both have different mechanisms due to the large gap in their emergence, so comparing them actually cannot be detailed.
Viewed from an investment perspective, it is clear that Bitcoin is more accessible which makes it easier for many people to get it... starting from $10 we can all have BTC... in contrast to gold which only targets rich people, because the price is expensive and there is a lower limit to buy gold is not lower than the lower limit of buying BTC.
In other words, Bitcoin is actually friendlier than gold, which is why we see a more rapid growth in Bitcoin interest from time to time.
