  The popularity of cryptocurrencies has grown significantly in recent years,
and they have become an important asset for internet trading. One of the main
drawbacks of cryptocurrencies is the high volatility and fluctuation in value.
The value of cryptocurrencies can change rapidly and dramatically, making them
a risky investment. Cryptocurrencies are largely unregulated, which can
exacerbate their volatility. The high volatility of cryptocurrencies has also
led to a speculative bubble, with many investors buying and selling
cryptocurrencies based on short-term price fluctuations rather than their
underlying values. Therefore, how to reduce the fluctuation risk introduced by
exchanges, transform uncertain prices to deterministic value, and promote the
benefits of decentralized finance are critical for the future development of
cryptos and Web 3.0.
  To address the issues, this paper proposes a novel theory as Automatic
Increase Market Systems (AIMS) for cryptos, which could potentially be designed
to automatically adjust the value of a cryptocurrency helping to stabilize the
price and increase its value over time in a deterministic manner. We build a
crypto, WISH (https://wishbank.wtf), based on AIMS in order to demonstrate how
the automatic increase market system would work in practice, and how it would
influence the supply of the cryptocurrency in response to market demand and
finally make itself to be a stable medium of exchange, ensuring that the AIMS
is fair and transparent.
