The last time I saw Ah Jie was three years ago. Back then, because he was a major client of our company, he was invited by us to discuss business development. At that time, he was mainly engaged in the business of selling mining machines (i.e., high-performance desktop computers). However, unlike ordinary Bitcoin mining farms, his four mining farms were not primarily engaged in mining but provided storage space to cloud companies. The mining machines were sold to the general public. Apart from his own fifty mining machines, the rest were held in the names of clients. The operation was somewhat similar to the multi-level marketing of the pyramid scheme industry. He sold a mining machine to A at a certain price and charged a monthly fee to manage the maintenance and operation of A's mining machine. A's mining machine not only had the chance to mine Bitcoin (actually just a promotional strategy) but also received certain rebates regularly for providing storage space. As long as A referred B and C to invest in mining machines, A would receive certain commissions, and so on. It is said that the price of a mining machine was HK$160,000, and he already had nearly 200 clients. Because his mining farms mainly focused on storage space, which coincided with the services of our Protocal Labs (or perhaps he deliberately catered to our business needs), he became one of our partners.
