Q&A on Bitcoin-related questions

- It's impossible for everyone to check the source code of the wallet they use; if everyone feels insecure, how can we be sure that the private key generated by a certain version of a wallet used three years ago is truly random?

Generally speaking, you can check the community of the wallet you are using. If the community's response is calm, the likelihood of issues is low.

From my observation, some well-established wallets (especially those with strong communities abroad) have not reported significant problems recently, because many people are monitoring those wallets. If there are issues, it is not easy to keep them hidden overseas.

Additionally, you can use multiple wallets to handle your assets separately, which reduces risk.

Overall, I believe that for the average user, cautiously checking and operating is a manageable risk.

I thought about this issue a long time ago, and here’s my understanding: it’s a game theory problem, and the key is how to maximize the use of information asymmetry between both parties.

In classic game theory problems (the prisoner's dilemma), the reason prisoners ultimately confess to their opponents is that one prisoner does not know how the other will respond, and there is a significant possibility: as long as the other confesses, they have no advantage. In this case, it inevitably leads to one or both parties confessing honestly.

This possibility traps the prisoners and gives their opponents a firm grip on them.

However, in Bitcoin, it is possible to eliminate that "significant possibility," meaning that only you know your private key. And you are very clear: as long as you don’t speak, no one else can take your assets. More importantly, your opponent cannot verify the authenticity of your response.

So in the case of Bitcoin, your advantage is better than that of the prisoners in the prisoner's dilemma. In this situation, you have relatively greater decision-making power.

- What do you think of Han Feng's stablecoin project pegged to Bitcoin?

I have great respect for the project teams that are still trying to expand or develop the ecosystem in Bitcoin, but I hold a cautious attitude towards the prospects of these projects.

A few years ago, I met Han Feng in Hong Kong. It was at a project roadshow where I saw him presenting his new project. I remember it was a Bitcoin layer two expansion.

At that time, I hardly absorbed any of the content he presented; the only deep impression I had was a sense of the passage of time and how quickly it flies.

Han Feng is considered one of the early pioneers in promoting and popularizing the crypto ecosystem in China. During that era, they experienced a shining moment in their crypto ecosystem. However, since then, that group of people seems to have gradually faded from the stage, especially as they appear to be falling behind the latest developments and pace of the crypto ecosystem.

I still have many such people in my social circle. Although they did not have the spotlight like Han Feng, they were all my entry-level teachers in this field and provided me with various insights.

However, today, 99% of them have exited the crypto stage: some are doing express delivery, some are in health care, some are in marketing, some are running franchise stores, some are speculating in the stock market, and some have shifted to artificial intelligence…

But none of them are posting about their footprints and activities in the crypto ecosystem anymore.

Sometimes I wonder: do they still reminisce about that time, and do they still pay attention to the crypto ecosystem?
