I think digital gold is more appropriate, not physical gold which has form and value, besides gold and btc have very different characteristics.

Bitcoin can be used as a currency on 2010 when Laszlo bought 2 pizza with 10,000 Bitcoin.
Bitcoin has been accepted in many online marketplaces.
Bitcoin already have many investors from institutional and government.
Bitcoin has been accepted as a legal tender in 2 countries e.g. El Salvador and Central African Republic.
Bitcoin already prove it can survive for 13 years so far, unlike shitcoins who died after 1-2 years.

With those achievement of Bitcoin itself, how you can say it wouldn't happen soon and unlikely to happen? I guess you're come from where Bitcoin were banned in your country, that's why you didn't see so many update, development and adoption of Bitcoin.

Talking about how valuable an asset because it just have a physical appearance, you're didn't understand about Bitcoin at all.

Bitcoin will surely become the new reserve for currency and finance institutions and they will create alternate coins, whose value be based on the reserve value of bitcoins used for hedging. In this way the whales will make money for each transaction done against their own currencies.
So in that way bitcoin will become what gold is today. The reserve currency.

That is Wonderful.. I am a firm believer in crypto space and BTC but I am also a believer that Gold still shall have its own value especially during the time of war and uncertainty.

In my opinion bitcoin, even in the future, will exceed gold from its price value, because the supply of bitcoin is limited. only 21 million. if the amount of gold can be categorized, there is no limit, as long as many people are mining gold, let alone new
recently heard the news, that uganda found 31 million tons of gold.

It would be awesome if the US decides to do that, but I don't think it's very realistic right now. The volatility in the bitcoin market is still too high for it to be a good store of value for everybody. Historically the Gold price has kept it's value for a long period of time, we haven't seen a price drop of 50% in a few months before with it. That is why it's so attractive for the older generation as an investment to store value. With the high volatility in bitcoins I would also not recommend my grandmother to invest in it. She is above 90 and at her age I advice against investing in stocks or cryptos, she still holds a bit of gold but the most she invest in is short term bonds. For the younger generation this completely different, the longer the investing horizon I would recommend to invest in cryptos rather than gold. The thing with gold is that it's good to store value, but you have no more upside potential. There is no chance that gold will rise 50% in the next 6 months, whereas with crypto currencies you can store your value long term as well and still have a chance to make a nice profit.

If you use gold as a metaphor, it's cool, because we are all going through this bitcoin era, and we feel that too. And every Bitcoin lover believes its future is far beyond now. Gold has created its own place in history and now I hope Bitcoin is the creator of the future.
