Investment thesis

Founded in 2017 out of a passion for blockchain and cryptocurrency, Block by Block Capital began with crypto arbitrage and proprietary trading between Korean and global markets. It later built a prop trading arm and launched KRWb, described as the first Korean Won fiat-backed stablecoin, which it exited in 2019. The firm diversifies across various investments and regional opportunities and has scaled a technical trading team to capture opportunity in 24/7 crypto markets, operating a systematically driven quant fund. It maintains a global footprint across Singapore, Korea, and the USA and emphasizes supporting the growth and adoption of the crypto industry.
