investment of over $14 billion
See, that is the problem right there. Many people here are very unsophisticated. They can't discern the difference between '$14 Billion investment' and '$14 Billion valuation'.
Because these very stupid people can't understand these very different concepts, they just keep on buying, and buying. Thus, we have a 'natural Ponzi scheme'. Bitcoin offers no utility nor function to anyone. It is simply a 'buy and hope' speculator's tool. There is no revenue. There are no earnings. It is just a more inflated 'market cap' day after day. A total Ponzi scheme.
Well the same could be argued about a parcel of land that your family has owned for generations. They might have bought it for $500 a hundred years ago but now it could be valued at $1 million. Zero investment has gone in and it has not grown in size. However, it does not make it a Ponzi.
Meanwhile the same acreage in some desolate par of the world is worth pretty much 0 and has not gone up in value at all.
And how it can affect the value of bitcoin or loss of importance to Fiat. Everything goes on as usual for sure.
