Bitcoin is not a ponzi scheme. It is not a pyramid. It is not even primarily a transactional currency.
Bitcoin is a reservoir; a store of value.
The reason Bitcoin has experienced the volatility and recent bubble is because capital was flowing into the fledgling economy with an expectation of something different than what it was, not to mention the lack of maturity in the system. The mere fact that the Bitcoin system has survived is incredible and a testament to the elegance and resilience of the underlying structure.
Understanding
stock and flow and
demand elasticity is critical. The former determines the depth of the reservoir while the latter determines the breadth. Bitcoin is still relatively shallow and small in width, so the volume of capital it can support remains limited.
The above compares the inflation rates and stock-to-flow ratios of Bitcoin and gold (all values starting from 2009 at a base of 1 and showing relational change thereafter;
data sources available at bottom of linked page). With gold, both variables have been steady for a very long time (gold production shows the cumulative amount mined, from which the inflation rate can be inferred - that's historically been a little over 1.5% per annum).
A stable medium such as gold (and
eventually Bitcoin) can store an unlimited amount of wealth so long as sufficient divisible units are available to maintain liquidity matching the level of demand. Bitcoin is in an early growth phase, so current behavior and performance are
not fully indicative of what there will be as a mature system. The system will approximate historical gold performance by the 2016-2020 period at the earliest. That should also be about the time frame in which division of full Bitcoins into Satoshis starts to become a necessity.
Paper fiat money (EUR, USD, etc) is a natural counterpart for Bitcoin & gold in that it functions to maintain stable price levels by allowing unrestricted amounts to be created in order to match economic growth. Bitcoin & gold act as safe, long-term repositories for stored wealth that are affected by, but not dependent upon economic activity the way fiat currency is.
This table shows how the two types of money interact:
Think of Altcoin as the translation layer between a consistent measure of value (Bitcoin or gold), and the fluctuating quantity and quality of goods and services in an entire economy. It doesn't matter whether there are 10,000 potatos or 1,000,000 - the price for them will still be the same in Altcoins. The more potatos there are, the cheaper they become in Bitcoins. Assume that potatoes are the only goods in our example economy, a maximum for Bitcoin of 1,000 Satoshis and an initial 10:1 Altcoin/Bitcoin to potato ratio:
Annual Potato Yield | >Total Altcoins | >Value in Altcoins | >Total Bitcoins | >Value in Bitcoins |
100 | 1,000 | 10 | 1,000 | 10 |
1,000 | 10,000 | 10 | 1,000 | 1 |
10,000,000 | 100,000,000 | 10 | 1,000 | 0.0001 |
Can you imagine if potato crop yields fell significantly one year and people saw the US dollar-denominated price of potatoes go from $1/ea to $10,000?
Now under a fixed 2% annual rate rise for Altcoins, with the same starting assumptions as above:
Annual Potato Yield | >Total Altcoins | >Value in Altcoins | >Total Bitcoins | >Value in Bitcoins |
100 | 1,000 | 10 | 1,000 | 10 |
1,000 | 1,020 | 1.02 | 1,000 | 1 |
10,000,000 | 1,040 | 0.000104 | 1,000 | 0.0001 |
The same problem arises as that with Bitcoin. A fixed absolute value increase would obviously be even more divergent. You can see from these tables that it is impossible for Bitcoin to serve both purposes alone. A second, more flexible Bitcoin system is necessary in the vein of Altcoin.
Bitcoin, like gold, is for saving and major transactions. Fiat is for day-to-day spending/trading. A Bitcoin-like variant that behaves like fiat would provide the spending functionality that most people are trying to force Bitcoin to do. Trying to force one system to act as both is impossible, as even with a perfectly-balanced approach (such as demurrage, which acts to address a management issue that the Bitcoin system inherently solves), divergences eventually lead to catastrophic failure. Two functionally independent systems can interact effectively for an indefinite period of time, all else being equal.
