In the world of Digital Money, a user with the username 999 published profound insights on Bitcoin investment in 2021. Although the original text has disappeared due to account bans, the wisdom contained within is still worth our review and contemplation today.

This user pointed out that the limited total supply of Bitcoin essentially makes its acquisition process a zero-sum game. No matter how one obtains Bitcoin, there will inevitably be others who lose an equivalent number of coins. More critically, as the number of holders increases, the share of Bitcoin that each person can obtain continuously decreases, making it a daunting challenge just to maintain the same amount of holdings.

The author emphasizes that in this zero-sum game, overly high expectations can lead to disappointment. He suggests that we should focus more on positive-sum games that can benefit all participants. Specifically regarding Bitcoin trading, the strategy of buying low and selling high may seem feasible, but in reality, it carries extreme risks. Especially with the constant influx of new participants, once an individual's coin holdings start to decline, it is easy to fall into psychological collapse, ultimately leading to bankruptcy.

The article also points out that exchanging Bitcoin for other small coins in hopes of gaining more Bitcoin is essentially a zero-sum game. Because one person's gain inevitably means another person's loss. Even Bitcoin mining is no exception; most miners could have more coins now if they had initially used all their funds to buy and hold Bitcoin.

This analysis delves deeply into the dilemmas and risks of Bitcoin investments, reminding us to maintain rationality and caution in digital money investments. While the Bitcoin market is full of opportunities, it also harbors crises, and investors need to fully understand its operational mechanisms and carefully assess their risk tolerance.
