In early 2017, due to some fortuitous circumstances, I got involved in investing in a cryptocurrency mining pool. Thanks to the crazy surge in cryptocurrency values that year, I made some money and still hold onto some BTC.

Because of this, in 2018, I once considered dedicating all my energy to the blockchain industry. However, after nearly half a year of in-depth research, I felt that it was really hard for the technology to generate practical value. By the way, I am a computer engineer with over ten years of work experience, having worked at some of the world's largest internet companies. So, blockchain technology was not magical to me.

I mean, the designs of BTC and ETH have their clever and interesting aspects, but at that time, I really couldn't see their practical application value. Therefore, I later diverted my time and career elsewhere. But I still worry that I made the wrong decision, so I kept a significant amount of BTC.
