In contrast to @Pxstar_, I decided to leave the stability and high salary of a big tech company and join the crypto industry during the "apocalyptic atmosphere of the global pandemic." I'm also a liberal arts major. I started to build my belief by self-studying cryptographic hash functions and merkle trees every night. After filling up a whole notebook, I finally felt confident enough to start applying for jobs. My teammate who introduced me to the crypto world once gave me a scarf with a phrase embroidered on it: "Time is Bitcoin." He bought his first BTC when the price was 2,000 RMB. Therefore, I choose to be a friend of time, and also a friend of BTC.
