Yes, the market cap of all crypto currencies combined has reached 1 Trillion US dollars, see also top line ticker here. I have predicted this 3 years ago, after the market collapsed, and now it is a fact: we are past 1T$, however much market cap valuations of this kind are highly questionable.
Unrealistic inflation of figures reported is common in competitive technology sector: look at all advertisements about speed of computer hard drives… totally unrealistic figures and fake news. However we accept the bitcoin market cap benchmark, simply because everybody uses and understands it. It is a de facto standard.
If we compare it to gold and some bankers actually agree with that, the total market cap of all gold on our planet is about 3 trillion (estimates vary). Gold is also subject to HODLing by US and Russian government etc. A tiny quantity of gold is actually ever exchanging hands: similar to bitcoin. An artificial valuable commodity manipulated by powerful actors.
Conspiracy theories suggest that All Time High (ATH) should happen on 9 January, anniversary of the bitcoin Genesis block, and here we are: bitcoin crosses 40 K exactly 3 years after reaching 20K. This confirms the idea that these markets are manipulated (by banks, governments and rich investors). Market manipulation is basically allowed!
Now both bitcoin and gold are actually valuable BECAUSE these powerful actors care about them and because of their tremendous brand value and popularity. Hundreds of millions have been spent on software development and on mining hardware etc. This alone explains the intrinsic value of bitcoin.
So far as of 2021 bitcoin lags behind gold. 12 years after creation bitcoin is still young. In fact, way fewer investors and bankers believe in bitcoin than in Gold, and it is going to stay that way in 2021. Bitcoin is a hard sell in the world of investment managers but eventually people see that no, Gold is not a great investment either but both can be used for portfolio diversification. We probably need another big cycle, wait until 2025 or 2030 for digital currency to become more important than gold. And the winner will probably not be bitcoin, but something technically vastly superior. The Google of cryptocurrency, doing the job right and achieving worldwide dominance… which has probably not yet been invented…
This will however inevitably happen in my opinion. One day crypto currency will reach 3 trillion and gold will continue being eroded. I can hardly imagine otherwise just for practical reason: digital currencies and gold are simply siting at two opposite sides of the spectrum on practicality and relevance in the modern economy.
In the long run, the winner is the digital currency. It will inevitably take over the world and pass the 3 trillion mark and I expect that this will happen in the next decade: before say 9 January of 2030.
