crypto is really amazing. It brings so many hopes.

I first read the Bitcoin white paper around 2017 for a _cryptography and network security_ lesson in university. I first bought Bitcoin using the CEX Huobi near Christmas in 2019, which is about two years later. Only recently did I began to pay attention to DeFi and a lot of new things.

Hello new new world!
